Contribute

Best contribute to [upstream](https://github.com/pnpnpn/retry-decorator) project, but it _might_ be abandoned. Also its defaults will be different from this project, unless [PR21](https://github.com/pnpnpn/retry-decorator/pull/21) (which is the reason for this fork) is accepted.

So… it’s up to you which project you raise your PR against, but contributions are welcome.
