Publishing

1. Update Cargo.toml and CHANGELOG.md to the new version.
2. Update lockfile: cargo check
3. git commit -m "Set version: XXXXXX"
4. Login to crates.io with your Github username. If you are a new user, you'll need to login and go to https://crates.io/me to verify your email address, and generate a new token. You can then cargo login <token>.
5. cargo publish. If it fails, you need to verify your email first, and/or be invited as an owner of the project.
6. git tag vXXXXXX (mind the leading v)
7. git push && git push --tags
