Subject: [PATCH] Voice Dump, Mute, Omni Mode via MIDI
Voice Dump Request via SysEx: MiniDexed now listens for the specific SysEx message (F0 43 20 00 F7) and sends the voice dump for the requested channel.
Mute Operator via SysEx: MiniDexed now handles the SysEx message for muting operators (F0 43 11 01 1B 2F F7) and toggles the mute state of the specified operator.
Omni Mode On/Off via MIDI CC: MIDI CC 124 and 125 are now handled to switch Omni Mode Off and On, respectively.
