Research direction

Start by reading the linked rasterstats documentation for working with categorical rasters and locating the existing zonal_stats entry point in xvec. Determine whether categorical rasters are already supported and define how count or area statistics should behave. Done means the requested categorical-raster statistic is supported and verified by appropriate tests.

Written by the indexing model from the issue text.

Description

I just had someone ask about zonal_stats with a categorical raster where the only "stat" that makes sense is a count (or perhaps area). Example: https://pythonhosted.org/rasterstats/manual.html?highlight=categorical#working-with-categorical-rasters

Is this supported or straightforward to implement?
