Research direction

Start at the filter_by_coordinate_system("X") entry point and reproduce the behavior with a coordinate system name that is absent. Trace how the filtered SpatialData object is created and add a regression test for the invalid name. Done means the call reports that the coordinate system does not exist instead of returning an empty object.

needs: triage priority: low

If a SpatialData object contains the following:

If we filter by an incorrect coordinate system name:
sdata = sdata.filter_by_coordinate_system("X")

This returns an empty sdata object.

An error message would be good to inform that the coordinate system doesn't exist.
