feat(cartridge): handle MBC-less games like tetris

TODO: This will panic whenever a write is attempted on the MBC-less
cartridge. This would be fine if games held the implicit rules given by
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)

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

feat: implement HALT behaviour
...
note: while the logic is there, the instruction currently does not do
anything because we don't halde it in Cpu::step(). The code that does is
currently commented out and there should be some underlying bugs still
present. Nevertheless it is a good start
