performance optimisation: sort polygons in shortcuts according to area #301
Description
currently the shortcuts contain a list of polygon boundary ids sorted after the total size of the polygons of each zone.
it would be more performant to sort them after tha actual area each boundary overlaps with the shortcut. assuming uniformly random distributed query points, the covered area corresponds to the probability of a query point lying within that polygon. use utility libraries (just installed for development) for this area computation.
