FR: Support sending MIDI Program Change

[ericpeters0n]

Program Change is just a standard MIDI message!

Status Byte
1100NNNN (where NNNN is Channel in binary)

Data Byte
0PPPPPPP (0 + the new program number)

New to the codebase. Anyone familiar know where this would need to be added?

Appears a midi_stream_program_change() function similar to this could easily handle the dispatch of the message:

Midi_Fighter_Twister_Open_Source/src/midi.c

Line 367 in e7f6c8f

void midi_stream_sysex (const uint8_t length, uint8_t* data)

[ericpeters0n]

This would be invoked by e.g. this process_encoder_input_switch function for configured button presses.

Midi_Fighter_Twister_Open_Source/src/encoders.c

Line 848 in e7f6c8f

void process_encoder_input_switch(uint8_t i, uint8_t virtual_encoder_id, uint8_t banked_encoder_id, uint16_t bit) {
