Description

https://github.com/Open-EO/openeo-processes/issues/404 added specification what should happen when negative buffering of small geometries with vector_buffer: use empty geometries.

Current implementation in openeo-python-driver however throws an error. Originally it was an obscure error message (see https://github.com/Open-EO/openeo-geopyspark-driver/issues/314). The error was improved in https://github.com/Open-EO/openeo-python-driver/issues/164 as quick fix.

Next step is to introduce empty geometries (and support them in subsequent processes like aggregate_spatial) instead of throwing errors.
