Still comes with it. libpysal requires geopandas (not geopandas-base).

[jGaboardi]

So:

• If matplotlib comes with geopandas through libpysal as a hard requirement, then it can't really be an optional one here, right?
• If it can be, is it even worth trying to figure out how to tests against not having it? I tried several ways of creating a minimum esda environment locally, but each way keeps pulling matplotlib.

We could change the conda-forge recipe to depend on geopandas-base there but I don't think it is worth the hassle.

Closing for now. We can look into again as time/energy permit.
