Ci updates

[bhazelton]

Update the CI to build against:

• linux, mac and windows (currently not working, but will be fixed by removing the healpy dependency swap astropy-healpix for healpy #75)
• the newest releases of our dependencies -- critical to make sure we're keeping up
• the oldest allowed versions of our dependencies -- critical to make sure our dependency ranges are accurate.

Also updates the minimum python to 3.11 because the minimum pyuvdata requires at least python 3.11. This also required updating the uv.lock file.

I also added uploading to codecov. I strongly prefer this to the current "roll our own" approach, however this can only represent coverage from the CI runs, so coverage is rather low. This will improve as we reduce our test data volume and get more code covered by the ci-runnable tests. For now I didn't add the codecov badge to our readme since it doesn't represent the true code coverage.

@nicholebarry I think this is ready and can go in as is, it at least improves the structure for future runs.
