Geometry Nodes: Edge Angle Node

Calculates the angle in radians between two faces that meet at an edge.
0 to PI in either direction with flat being 0 and folded over on itself PI.
If there are not 2 faces on the edge, the angle will be 0.

For valid edges, the angle is the same as the 'edge angle' overlay.

For the Face and Point domain, the node uses simple interpolation to calculate a value.
