Add hooks for zoneinfo.ZoneInfo

[makukha]

Many thanks to authors of cattrs for the minimalistic design and simplicity!

Do you think it is reasonable to add more hooks, covering frequently used classes from stdlib?
In this specific case I mean zoneinfo.ZoneInfo, both structuring and unstructuring.

I probably could come up with PR for this.

Hi,

Thanks for the offer. The problem with adding these less commonly used types is that they add a tiny bit of overhead to converter startup, and possibly the import time, and this has to be borne by everyone.

What we could do is add a section to the recipes doc with hooks for these stdlib types. I'd merge that in no problem.

Going to close this now in an attempt to keep the issue list manageable. 😇

Got it, this makes sense.
