spectral: Add Spectral NR example
...
Add Spectral NR example. Example switches between
'passthrough' and 'Spectral NR' processing every 10
seconds to allow comparison.
Input is via I2S and USB. Output is on I2S/headphones

full resolution for I2S input, all 32 bits are read and converted to float (instead of only upper 16 bit)

Added float modules for 24 bit precision S/PDIF I/O. They are forked from current code of the "offical" (16 bit 44.1kHz only) Teensy audio library, but extended to 24 bit precision and configurable sample rate.

I2S output was sending 32 bits already, but only 16 were used. Now, send all available precision.

Basically, I re-did jcj83429's pull request, which got outdated, to current code: https://github.com/chipaudette/OpenAudio_ArduinoLibrary/pull/8
