Attached is a tiny portion of large tessellation which contains overlapping polygons. Only very tiny overlaps, but overlaps nevertheless. This causes shapely.coverage_union_all to fail. We should ensure that the result of tessellation is a clean topological coverage.

I guess that some internals of the tessellation algo are in a need of refactoring but I am really not looking forward to that as that code is a beast.

One pathway to explore is to use GEOS instead of SciPy to generate the diagram. Unsure about performance but shapely gives us back polygons.
