Update and relax versions and package requirements

Users have wanted to use gdptools with python=3.10. gdptools had been pinned to python=3.9. I relaxed the package dependencies and added python=3.10 and incorporated 3.10 into testing. Could not get 3.11 to work because of the numcodecs package would not build, related to dask. Will try again in the future as 3.11 becomes more mature.

@arschultz - please review and if testing pipeline passes, please merge.
