Key split tables have been given names based on usage (KeySplitTable1 -> keysplit_piano etc) and a new macro has been set up to better represent the individual bytes for key splits with it being more obvious to how said bytes are used for the respective voice in the voicegroup.

mid2agb has been modified to allow more than just numbers when naming voicegroups and voicegroups have been renamed to match. A "voice_group" macro has been set up with a optional parameter for the starting note will shift the offset by the specified amount * 0xC which is the length of 1 voice in a voicegroup. All drumset voicegroups have a "starting_note" of 36.
