v0.2.0

Fixes & Additions

• Revamp of voronoi clipping logic to fix several bugs in degenerated edge cases
• About 20% faster voronoi cell building when ClipBehavior::Clip is set compared to v0.1.1
• Voronoi cell edges are now deduplicated after clipping
• VoronoiCell::iter_vertices() now implement Clone
• Fixed bug in NeighborSiteIterator that incorrectly returned neighbor sites on the hull when their connectivity was severed due to voronoi edge clipping
• Added TopologicalNeighborSiteIterator which checks connectivity on delaunay graph only and does not care about voronoi edge clipping
• Voronoi now implements Clone

Breaking

• Changed library interpretation of Y axis to point downwards to conform with delaunator convention

Bounding box

• Removed enums related to edges
• which_edge() now returns the index of the edge where the point is or None
• EdgesAroundSiteIterator and NeighborSiteIterator now return edges clockwise (due to Y axis convention change)

VoronoiCell

• Removed iter_triangles(). Replaced with triangles()
