Yeah I'm using it to serialize the output lines as a TSV. Rust's `println!` is notoriously slow and using `csv` to serialize the output is a nice way to boost throughput

Thanks. Nice find! Though it feels weird to have to use a csv crate for that. Ideally the `fast printing` part should be understood, and either used directly, or extracted as a separate, smaller crate.
