ARCH CURVE SIMPLIFY

Implementation of the Ramer–Douglas–Peucker algorithm to geometry node user interface. There are many ways to refine the algorithm, so far I added the curve point angle for poly and curve point handles angle for beziers, options to keep original bezier points or use custom selected points. The maximum iteration limit should be handled for worst split case in the background, so the exposed parameter gives sense only when you need to see the steps from start.
