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)

83c178413d tests: Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience. 2023-03-28 08:57:24 -05:00
fbc0a0b2ea tests: Coverage and cleanup/speedup
- Improved test coverage to >80% of lines, functions
  - When doctests are included.
  - Wrote new unit tests:
    - Explicit tests for invalid instructions in the
      ranges {`5xyn`, `8xyn`, `9xyn`, `Fxbb`}
    - `rand` Tests for 1052671 cycles, to ensure
      randomly generated number is < ANDed byte
    - `Ex9E` (sek), `ExA1`(snek) will press only the expected key,
      then every key except the expected key, for every address
    - `Fx0A` (waitk) asserts based on the waveform of a keypress.
      After all, an A press is an A press.
- Improved test performance by printing slightly less
- Removed nightly requirement
  - (now optional, with feature = "unstable")
- Amended justfile to test with `cargo nextest` (nice)
- Changed release builds to optlevel 3
