Adds a heuristic check that the OverlayNG result area is consistent with the inputs and the overlay operation.
Prevents erroneous results for some cases where noding is vector-clean (and hence not caught by noding validator), but causes a vertex to cross a segment and thus "invert" an area in the topology graph.

Fixes #798 and #808.
