Rewrote the disassembler and cpu::tick() for code concision and massive speed improvements.

Turns out, getting the current time takes AGES, so if we don't need it, we don't get it.

Refactor disassembler to use imperative-rs f60a4b3cc2

It's like MAGIC. Easily cut out 200 LOC

cpu.rs: Fix some documentation errors 8ab9799913

Major Refactor: Make invalid states unrepresentable™️ cc3bc3a7fe

- Rewrote the instruction decoder as an enum
- Used imperative_rs to auto-generate the bit twiddling logic
- Implemented Display on that enum, for disassembly
- Rewrote CPU::tick
  - Now >10x faster
  - Disassembly mode is still 5x slower though
- Implemented time-based benchmarking
  - (use option -S to set the number of instructions per epoch)
