Merge branch 'imperative-rs'
...
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.

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)

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
