Subject: [PATCH] updates midi functionality (#331)
* implements leader key for planck experimental
* allows override of leader timeout
* adds ability to use the leader key in seq
* fixes leader keycode
* adds chording prototype
* fixes keycode detection
* moves music mode to quantum.c
* disables chording by default
* adds music sequencer functionality
* implements audio/music functions in quantum.c
* splits up process_action to allow independent processing of actions
* moves midi stuff to quantum.c
* adds additional scales for midi
