Rekai Nyangadzayi Musuka 6db132ad48 feat(cartridge): handle MBC-less games like tetris

the hardware, however this is not the case. We will have to modify the
NoMBC implementation to ignore writes to the cartrige (while still
documenting them just in case of bugs)

Rekai Nyangadzayi Musuka 2bf877d1ec fix(cpu): Ensure mask the high bits of the flag register 
There was a bug where POP AF returned 0x1301. In this example, the A
register would be set to 0x13, and the Flag register woud be set to
0x01, which is an invalid state considering only bits 4 -> 7 of the flag
register are used. This commit masks the flag register with & 0xF0
whenever it is read or written to so that we can ensure that only the
high bits can ever be potentially set

Rekai Nyangadzayi Musuka a82e3d3372 feat: implement HALT behaviour 
note: while the logic is there, the instruction currently does not do

currently commented out and there should be some underlying bugs still
present. Nevertheless it is a good start
