Support all geom types in Voronoi Graph builder

[martinfleis]

With #678 in, I suppose we can allow Voronoi weights builder for any geometry type. We just need a documentation and pass the args to voronoi_frames.

i think this is resolved?

[martinfleis]

It is not. We are still checking for Point input and are not passing kwargs needed for polygonal support (shrinkage, segmentation...)
