Stat / Class Expansion FE6 & FE7

While nothing as powerful as expanded modular save, this hack just shuffles around a few bits here and there to allow the following:
- Level & Stats up to 63
- Characters up to 0xFF (in fe6, characters above 0x7F aren’t saved properly between chapters otherwise)
- Classes up to 0xCF or so (classes past this might have their map sprites break like in fe8)
Please note that installing this will break old save files.
