Additional maintainers

Would you consider adding more maintainers to this repo, or potentially transferring it to some group where you can add more maintainers?

@hugovk I think given that this project is still mostly unmaintained isodate2 will eventually be needed again if we want type hints (like @eggplants tried to add here) and other enhancements, maybe it would be best to unarchive it?

Can do!

Or: after this repo was revived, looks like I reused the isodate org I created for something else and removed my fork from it. I think I still have a local clone on another machine so can re-upload it.

However I don't have time to maintain a fork at the moment, so you and/or others would need to do that, but I could help get it up and running and share/handover access to https://pypi.org/project/isodate2/.

The difficult bit is: as this repo is sort semi-maintained/semi-unmaintained, should the fork just go its own way (the easy choice for a completely unmaintained repo), or should it try and remain somewhat in sync with upstream...
