Rekai Nyangadzayi Musuka b13444c885 feat(snd): simplify audio buffer
continuous-integration/drone/push Build is passing Details
The audio buffer now is held by crossbeam. The developers of said
library could write a batter queue than I could anyday

Rekai Nyangadzayi Musuka 3b772c7c49 feat(snd): synchronize audio with rest of system
In it's current form I think this is actually rather inefficient. It's
also not very accurate since I throw away a lot of samples for no real
good reason. More improvements to thiss will be coming henceforth

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
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
