Several fixes:

- moved "StaticJsonDocument<JSON_BUFFER_SIZE>" to JsonDocument as StaticJsonDocument is marked depriciated.
- Fixed display_plus show()-method
- Fixed string length for drumset sounds
- Newer version of third-party libraries

-> ### BREAKING CHANGES
->
-> This release hides `JsonVariant`'s functions that were only intended for internal use.
-> If you were using them in your programs, you must replace with `operator[]` and `to<JsonVariant>()`, like so:
->
-> ```c++
-> // before
-> JsonVariant a = variant.getElement(idx);
-> JsonVariant b = variant.getOrAddElement(idx);
-> JsonVariant c = variant.getMember(key);
-> JsonVariant d = variant.getOrAddMember(key);
->
-> // after
-> JsonVariant a = variant[idx];
-> JsonVariant b = idx < variant.size() ? variant[idx] : variant[idx].to<JsonVariant>();
-> JsonVariant c = variant[key];
-> JsonVariant d = variant.containsKey(key) ? variant[key] : variant[key].to<JsonVariant>();
-> ```

-> ### BREAKING CHANGES
->
-> #### Support for `char` removed
->
-> We cannot cast a `JsonVariant` to a `char` anymore, so the following will break:
-> ```c++
-> char age = doc["age"];  //  error: no matching function for call to 'variantAs(VariantData*&)'
-> ```
-> Instead, you must use another integral type, such as `int8_t`:
-> ```c++
-> int8_t age = doc["age"];  // OK
-> ```
->
-> Similarly, we cannot assign from a `char` anymore, so the following will break:
-> ```c++
-> char age;
-> doc["age"] = age;  // error: no matching function for call to 'VariantRef::set(const char&)'
-> ```
-> Instead, you must use another integral type, such as `int8_t`:
-> ```c++
-> int8_t age;
-> doc["age"] = age;  // OK
-> ```
-> A deprecation warning with the message "Support for `char` is deprecated, use `int8_t` or `uint8_t` instead" was added to allow a smooth transition.
->
-> #### `as<T>()` always returns `T`
->
-> Previously, `JsonVariant::as<T>()` could return a type different from `T`.
-> The most common example is `as<char*>()` that returned a `const char*`.
-> While this feature simplified a few use cases, it was confusing and complicated the
-> implementation of custom converters.
->
-> Starting from this version, `as<T>` doesn't try to auto-correct the return type and always return `T`,
-> which means that you cannot write this anymore:
->
-> ```c++
-> Serial.println(doc["sensor"].as<char*>());  // error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
-> ```
-> 
-> Instead, you must write:
->
-> ```c++
-> Serial.println(doc["sensor"].as<const char*>());  // OK
-> ```
->
-> A deprecation warning with the message "Replace `as<char*>()` with `as<const char*>()`" was added to allow a smooth transition.
->
-> #### `DeserializationError::NotSupported` removed
->
-> On a different topic, `DeserializationError::NotSupported` has been removed.
-> Instead of returning this error:
->
-> * `deserializeJson()` leaves `\uXXXX` unchanged (only when `ARDUINOJSON_DECODE_UNICODE` is `0`)
-> * `deserializeMsgPack()` replaces unsupported values with `null`s
->
-> #### Const-aware `is<T>()`
->
-> Lastly, a very minor change concerns `JsonVariantConst::is<T>()`.
-> It used to return `true` for `JsonArray` and `JsonOject`, but now it returns `false`.
-> Instead, you must use `JsonArrayConst` and `JsonObjectConst`.

-> ### BREAKING CHANGES
-> 
-> #### Copy-constructor of `BasicJsonDocument`
->
-> In previous versions, the copy constructor of `BasicJsonDocument` looked at the source's `memoryUsage()` to choose its capacity.
-> Now, the copy constructor of `BasicJsonDocument` uses the same capacity as the source.
->
-> Example:
->
-> ```c++
-> DynamicJsonDocument doc1(64);
-> doc1.set(String("example"));
->
-> DynamicJsonDocument doc2 = doc1;
-> Serial.print(doc2.capacity());  // 8 with ArduinoJson 6.14
->                                 // 64 with ArduinoJson 6.15
-> ```
->
-> I made this change to get consistent results between copy-constructor and move-constructor, and whether RVO applies or not.
->
-> If you use the copy-constructor to optimize your documents, you can use `garbageCollect()` or `shrinkToFit()` instead.
->
-> #### Copy-constructor of `JsonDocument`
->
-> In previous versions, it was possible to create a function that take a `JsonDocument` by value.
->
-> ```c++
-> void myFunction(JsonDocument doc) {}
-> ```
->
-> This function gives the wrong clues because it doesn't receive a copy of the `JsonDocument`, only a sliced version.
-> It worked because the copy constructor copied the internal pointers, but it was an accident.
->
-> From now, if you need to pass a `JsonDocument` to a function, you must use a reference:
->
-> ```c++
-> void myFunction(JsonDocument& doc) {}
-> ```

-
-> ### BREAKING CHANGES
-> 
-> #### NaN and Infinity
-> 
-> The JSON specification allows neither NaN not Infinity, but previous
-> versions of ArduinoJson supported it. Now, ArduinoJson behaves like most
-> other libraries: a NaN or and Infinity in the `JsonDocument`, becomes
-> a `null` in the output JSON. Also, `deserializeJson()` returns
-> `InvalidInput` if the JSON document contains NaN or Infinity.
-> 
-> This version still supports NaN and Infinity in JSON documents, but
-> it's disabled by default to be compatible with other JSON parsers.
-> If you need the old behavior back, define `ARDUINOJSON_ENABLE_NAN` and
-> `ARDUINOJSON_ENABLE_INFINITY` to `1`;:
-> 
-> ```c++
-> #define ARDUINOJSON_ENABLE_NAN 1
-> #define ARDUINOJSON_ENABLE_INFINITY 1
-> #include <ArduinoJson.h>
-> ```
-> 
-> #### The "or" operator
-> 
-> This version slightly changes the behavior of the | operator when the 
-> variant contains a float and the user requests an integer.
->
-> Older versions returned the floating point value truncated.
-> Now, it returns the default value.
-> 
-> ```c++
-> // suppose variant contains 1.2
-> int value = variant | 3;
-> 
-> // old behavior:
-> value == 1
-> 
-> // new behavior
-> value == 3
-> ```
-> 
-> If you need the old behavior, you must add `if (variant.is<float>())`.

 > ### BREAKING CHANGES
 >
-> #### JsonVariant
+> As every major release, ArduinoJson 7 introduces several breaking changes.
+> I added some stubs so that most existing programs should compile, but I highty recommend you upgrade your code.
 >
-> `JsonVariant` now has a semantic similar to `JsonObject` and `JsonArray`.
-> It's a reference to a value stored in the `JsonDocument`.
-> As a consequence, a `JsonVariant` cannot be used as a standalone variable anymore.
+> #### `JsonDocument`
 > 
-> Old code:
+> In ArduinoJson 6, you could allocate the memory pool on the stack (with `StaticJsonDocument`) or in the heap (with `DynamicJsonDocument`).  
+> In ArduinoJson 7, the memory pool is always allocated in the heap, so `StaticJsonDocument` and `DynamicJsonDocument` have been merged into `JsonDocument`.
 >
-> ```c++
-> JsonVariant myValue = 42;
-> ```
->
-> New code:
+> In ArduinoJson 6, `JsonDocument` had a fixed capacity; in ArduinoJson 7, it has an elastic capacity that grows as needed.
+> Therefore, you don't need to specify the capacity anymore, so the macros `JSON_ARRAY_SIZE()`, `JSON_OBJECT_SIZE()`, and `JSON_STRING_SIZE()` have been removed.
 >
 > ```c++
-> DynamicJsonDocument doc;
-> JsonVariant myValue = doc.to<JsonVariant>();
-> myValue.set(42);
-> ```
+> // ArduinoJson 6
+> StaticJsonDocument<256> doc;
+> // or
+> DynamicJsonDocument doc(256);
 > 
-> #### JsonPair
->
-> Old code:
->
-> ```c++
-> for(JsonPair p : myObject) {
->   Serial.println(p.key);
->   Serial.println(p.value.as<int>());
-> }

->
-> New code:
->
-> ```c++
-> for(JsonPair p : myObject) {
->   Serial.println(p.key());
->   Serial.println(p.value().as<int>());
-> }
+> // ArduinoJson 7

-> ### BREAKING CHANGES
->
-> #### Non quoted strings
->
-> Non quoted strings are now forbidden in values, but they are still allowed in keys.
-> For example, `{key:"value"}` is accepted, but `{key:value}` is not.
+> In ArduinoJson 7, `JsonDocument` reuses released memory, so `garbageCollect()` has been removed.  
+> `shrinkToFit()` is still available and releases the over-allocated memory.
 >
-> #### Preformatted values
+> Due to a change in the implementation, it's not possible to store a pointer to a variant from another `JsonDocument`, so `shallowCopy()` has been removed.
 > 
-> Old code:
+> In ArduinoJson 6, the meaning of `memoryUsage()` was clear: it returned the number of bytes used in the memory pool.  
+> In ArduinoJson 7, the meaning of `memoryUsage()` would be ambiguous, so it has been removed.
 >
-> ```c++
-> object["values"] = RawJson("[1,2,3,4]");
-> ```
+> #### Custom allocators
 >
-> New code:
+> In ArduinoJson 6, you could specify a custom allocator class as a template parameter of `BasicJsonDocument`.  
+> In ArduinoJson 7, you must inherit from `ArduinoJson::Allocator` and pass a pointer to an instance of your class to the constructor of `JsonDocument`.
