bezier curve and petals node

A node on a Baez curve, which I find very useful, is able to adjust the curvature like a pen tool.

Create a petal node, adjust the position, copy the node and connect it to the input, adjust the curvature position, you can get the effect of petal folding

The original node was made by Suzukimy, and I modified it on the basis.
