migrate criterion benchmarks to PLNK

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

 ## oneshot benchmarks
 these are benchmarks that run a single measurement, implemented as _examples_ in
 `examples/benches/`.
