Rekai Nyangadzayi Musuka 90d2da9272 chore(gui): implement basic disassembler 
Also implement CPU and Interrupt debug information.

Of note:
1. IE and IRQ status boxes are slightly misaligned
2. Whenever the disassembler accidentally reads into game data rather
   than executable code the emulator crashes
   * Thus I should turn Instruction decoding into a Result<> rather than
     panic on failure

Rekai Nyangadzayi Musuka 8625bec059 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.

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
