Sega Genesis coprocessor bus is now working
...
I've added skeleton devices for the sound chips, and added the bank
register and banked area of ram mapped to the Z80's bus. Sonic1 will
now run (if the ym2612 device's size is set to 0x1000 instead of 0x04)

Refactored ym7101 to store state unpacked
...
Previously it was storing data in the registers, which was an array
of u8, but now it's storing eg. full addresses for the scroll tables
so that they don't need to be fetched from the register values and
converted every rendering. I was thinking this would maybe make
DMA debugging easier, in particular.

Fixed issues with Genesis controllers and sprite rendering
...
The controller th count was starting at 1 instead of 0 which caused
inputs to be read incorrectly, as well as the fact that inputs are
inverted.
The sprite fix now draws them in the right order so that ComradeOj's
sprite test renders correctly, but games still render them broken
because of some other bug yet to be found

Fixed issue with colour 0 being the mask colour
...
For systems that legitimately use 0 for black, this causes a
problem, so I instead use 0xFFFFFFFF for the mask colour which
corresponds to transparent white in ARGB format, which minifb
doesn't support anyways

Fixed bug in MOVEM and added tests for it
...
It was previously decrementing addresses if the direction was from
registers to memory, but that's incorrect. It should increment the
address always when using an addressing mode other than the ARecDec
mode. I also added a memory location to the test cases to test the
MOVEM instruction by comparing what memory was read/written (but it's
only one u32 because that's the minimum we need)
