Drop py3.8 support for newest xarray version

[SeanLeRoy]

Description

A main dependency of this package, xarray, dropped support for Python 3.8 in version 2023.02.0. This has caused our upstream tests to fail (see here). Per the conversation in #475 I removed support for Python 3.8 in favor of supporting the newest xarray version.

A version of aicsimageio (4.10.0) has been released announcing end of its support for Python 3.8

Testing

Clean installed locally, unit tested locally

Assuming all tests pass, seems fine to me. Sad we don't have 3.11 support yet. We should re-run those tests to see if anything has changed on that front.

I think we have an open issue or PR for Python3.11.

Also we should cut a release with as many bugfixes as possible before dropping support for Python3.8. And document it as our last Python 3.8 release . (I see a potential maintenance branch in our future)

Should I cut the release now or just hold off on merging this until the bugs we have scheduled are done.

Closing for now, will re-open post last python 3.8 supported release
