Some uses of delaunay_2d_calc don't need to know the original verts, edges, and faces that correspond to output elements. This change adds a "need_ids" value to the CDT input spec, default true, which tracks the input ids only when true. The python api mathutils.geometry.delaunay_2d_cdt gets an optional final bool argument that is the value of need_ids. If the argument is not supplied, it is true by default, so this won't break old uses of the API. On a sample text test, not tracking ids save about 30% of the runtime. For most inputs the difference will not be so dramatic: it only really kicks in if there are a lot of holes.
