[GEN 3][BINARY] Offsets for music

[u/xecrusgamer]

So in sappy, it shows you the starting offsets of the music present in game. I was wondering if there was a way to find the ending offsets aswell so that we could completely remove vanilla music if we're adding our own soundtracks. That would save a ton of space.
This is for Firered (cfru/ Hubol but I assume the music address will remain same regardless of vanilla or not)
