#880: topology.AddFace speed up using prepared geometries

I belive the current topology.AddFace could be pretty much faster than it
is, especially for big polygons, composed by many edges, if the code used
prepared geometries implementation rather than computing full intersection
matrix for each candidate edge.
Early tests show improvements of up to 45%.
