feat: clock bus on instruction read-write
...
continuous-integration/drone/push Build is failing
Details
Commit also includes general work towards passing mem-timings.
Note: while cpu_instrs.gb passes, instr_timing.gb and mem_timing.gb both
are stuck in infinite loops (Currently, it seems like a timing issue).
This is a major regression that hopefully shouldn't last for too long.

In it's current form I think this is actually rather inefficient. It's

good reason. More improvements to thiss will be coming henceforth

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
