Mutation testing

This crate uses cargo-mutants for mutation testing in CI. To run it locally:

cargo install --locked cargo-mutants
cargo mutants

Compare the performance of two branches

git checkout branch1
cargo bench
git checkout branch2
cargo bench

The second cargo bench run will run various benchmarks and, for each one, report either "Performance has improved." or "Performance has regressed."
