Doom SNES with MSU-1 audio!

This adds CD quality music via the MSU-1 expansion chip.
The tracklist has been replaced with that of the original PC version, so every level has its proper music now!
This hack also adds circlestrafing and the ability to start any episode on any difficulty.
See the README in the included zip for setup instructions.

Version 1.1 adjusts the start time of MSU-1 track playback to line up with the original SPC700 music. (music starts when level is done loading now)

Version 1.2 rewrites the track loading code to ensure a better experience when playing the game on real hardware using an SD2SNES/FXPak Pro.
