* 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
