Update to v099r15 release.

Changelog:
- nall::lstring -> nall::string_vector
- added IntegerBitField<type, lo, hi> -- hopefully it works correctly...
- Multitap 1-4 -> Super Multitap 2-5
- fixed SFC PPU CGRAM read regression
- huge amounts of SFC PPU IO register cleanups -- .bits really is lovely
- re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU
  - but they're now optimized to the realities of the PPU (16-bit data
    sizes / no address parameter / where appropriate)
  - basically used to get the active-display overrides in a unified place;
    but also reduces duplicate code in (read,write)IO
