Add ISMIP6 Greenland region masks that extend beyond ice edge

[trhille]

This merge adds ISMIP6 region masks to the Greenland mesh, which extend beyond ice edge and will be useful for regional stats. It also makes use of the allTags argument when calling GeometricFeatures.read() instead of looping over tags for greater flexibility.

Note: This requires geometric_features version 1.4.0, which is not yet in the latest version of compass.

Testing

Here are the ISMIP6 basins on a 30–100 km GIS mesh:

The Zwally basins remain unchanged (I won't bother adding screenshots here).

Thanks, @xylar. What's the protocol for a PR like this that requires updates to the compass environment (geometric_features=1.4.0)?

[xylar]

Ah, missed that. You also need to bump to alpha.2 (maybe in a couple of places).

[xylar]

I'll push a commit to update geometric_features and compass itself. I'd also like to add a commit to make the ocean masks for these regions in files_for_e3sm if that's okay with you.

Tested on perlmutter with the default parameters and everything worked fine for me!

Also took a look over the code and everything looks good to me!
