Adds two new algorithms which expose QgsGeometry's methods for segmentizing curved geometries. "Segmentize by maximum distance": The segmentization is performed by specifying the maximum allowed offset distance between the original curve and the segmentized representation. "Segmentize by maximum angle": The segmentization is performed by specifying the maximum allowed radius angle between vertices on the straightened geometry (e.g the angle of the arc created from the original arc center to consective output vertices on the linearized geometry).
