I've added a lot of tests in this PR. Happy to cut them down if you think that would make it easier for other contributors to follow.

Just made a couple of small changes to make sure this is backwards-compatible 🙂

Thanks @mastrix for this PR - I hope you don't mind if I try to get it merged! -- Hey @Sigrsig and @steffektif 👋 I think you're the current maintainers...

Hi @Sigrsig & @steffektif, sorry for the nudge - are you still maintaining this project? If not, is there anyone else I should reach out to?

Thanks a lot @steffektif - appreciate it 🙂

Hi, @PreussHendrik and @crecotun! I'd really appreciate a review here - might one of you be able to take a look please? Let me know if there's anything I can...
