track_player.h

			supports per font (or common) track player function

			note: for each font where you want their own tracks to play, please make sure
			your preset has a font search path, and that you add the track folder like so:

			;font/tracks

			then create your tracks folder under that font, and populate it with 00xx.wav files

			note: if you want to share common tracks between fonts, try something like this:

			;common/tracks

			*/

			// track_player uses its own button to start playing trackXX.wav files
			// found anywhere in the font search path (see install info above)
			// TRIGGER + POINT UP to play NEXT track, TRIGGER + POINT DOWN to play PREV track
			// the original music trigger button STOPS the new track_player
			// and will also start/stop the original track player

			// another mode

			// check when track is finished, start the other track
			// until all are played through, then stop

			// next and previous track
