Tracking issue for cycles

[AlessioC31]

• Base structure
• Memory regions wait cycles (https://rust-console.github.io/gbatek-gbaonly/#address-bus-width-and-cpu-readwrite-access-widths):
  • BIOS
  • Work RAM 32k
  • I/O
  • OAM
  • Work RAM 256k
  • Palette RAM
  • VRAM
  • GamePak ROM (look at https://rust-console.github.io/gbatek-gbaonly/#gbasystemcontrol)
  • GamePak Flash
  • SRAM
• Move ppu, etc... to bus
• Check every instruction for I cycles
• Open bus behaviour (probably not needed for cycles) (https://rust-console.github.io/gbatek-gbaonly/#reading-from-unused-memory-00004000-01ffffff10000000-ffffffff)
