migrate criterion benchmarks to PLNK (dragoon/komodo!87)

## changelog
- benchmarks
  - _commit_ has been removed in favor of `examples/benches/commit.rs`
  - _linalg_ has been migrated to `examples/benches/` as `bench_linalg`
  - _setup_ has been migrated to `examples/benches/` as `bench_setup`
- `read-atomic-ops` command has been moved to `scripts/parse.nu` module
- `scripts/plot/bench_commit.py` has been made more general and renamed to `scripts/plot/plot.py`
- `scripts/plot/benches.py` has been removed because it's not required anymore => `plot.py` and `multi_bar.py` are general enough
