Ruff Benchmarks

The ruff_benchmark crate benchmarks the linter and the formatter on individual files:

# Run once on the "baseline".
cargo bench -p ruff_benchmark -- --save-baseline=main

# Compare against the "baseline".
cargo bench -p ruff_benchmark -- --baseline=main

# Run the lexer benchmarks.
cargo bench -p ruff_benchmark lexer -- --baseline=main

See CONTRIBUTING.md on how to use these benchmarks.
