processing: Add SFCGAL approximate medial axis processing
PR Description:
Description
This introduces a new processing based on SFCGAL backend:
The Approximate Medial Axis algorithm generates a simplified skeleton of a shape by approximating its medial axis.
The output is a collection of lines that follow the central structure of the shape. The result is a thin, stable set of curves that capture the main topology while ignoring noise.
This algorithm ignores the Z dimensions. If the geometry is 3D, the approximate medial axis will be calculated from its 2D projection
