PMP: Add a function to find edges with smallest/largest dihedral angle

[afabri]

Summary of Changes

Add an overloaded of the function detect_sharp_edges() to identify the non-border edges with smallest/largest dihedral angle.
It returns the edge descriptors and the angles in degree.

• Deal with non-triangle case
• What to do with edges adjacent to degenerate faces?
• Add to statistics in Lab
• Small Feature

Release Management

• Affected package(s): Polygon Mesh Processing
• Issue(s) solved (if any): fix #0000, fix #0000,...
• Feature/Small Feature (if any):
• Link to compiled documentation (obligatory for small feature) wrong link name to be changed
• License and copyright ownership: GeometryFactory
