Bump and relax xarray version requirement

[gjoseph92]

From #50 (@scottyhq):

Also, I'm wondering if it's possible to relax (^0) or bump (^0.18.0) the current xarray pin for the next release? Could add some matrix tests against xarray master to ensure things don't break since currently it does seem like minor bumps in xarray are more like major bumps ;) (#26 ).

stackstac/pyproject.toml

Line 43 in d1e15ca

xarray = "^0.17.0"

Probably should just relax it, though in this case we might actually want to bump—looks like there are a couple things in the new xarray version that will benefit stackstac visualizations (faster interp logic + fixed ffill). I might go with >=0.18, <1 for now.

stackstac 0.2.1 is out, give it a try!
