Registration: find better cropping algorithm

[ieivanov]

LIR is overkill as we are always looking for the overlap between rectangular volumes aligned with the coordinate system axes. LIR allows finding overlaps between polygons of arbitrary shape and it's optimization algorithm is a bit slow for what we need. It still works well, so this is not a blocker, largely a user-experience enhancement.

Maybe try https://github.com/planetlabs/maxrect, https://shapely.readthedocs.io/en/stable/reference/shapely.intersection.html or simple min/max operations on the vertices.
