cc3bc3a7fe Major Refactor: Make invalid states unrepresentable™️ 
- 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)
