HRA update to go along with pygeoprocessing #322

[emlys]

Description

Fixes #1881

The changes made in natcap/pygeoprocessing#428 caused an HRA test to fail, because HRA's geometry simplification function was always setting the vector geometry type to Unknown. pygeoprocessing.zonal_statistics will now require a type of Polygon or MultiPolygon, so this raised an error.

To resolve it, I am updating HRA to copy the geometry type over from the input vector. This may still be Unknown for habitat or stressor layers, but should always be Polygon or MultiPolygon for the AOI (which zonal_statistics is run on).

Checklist

• Updated HISTORY.rst and link to any relevant issue (if these changes are user-facing)
• Updated the user's guide (if needed)
• Tested the Workbench UI (if relevant)

Looks great, thanks @emlys !

Hmm something seems to be a little funky with GHA. I'll let it cook a little longer and see if the actions complete. Otherwise, this change is so simple I'm happy to just merge.

I fixed a whitespace issue that was causing the HISTORY.rst check to fail. The ReadTheDocs failure seems unrelated, so I'm going to merge
