Spiralize Closed Contours in Deburr

The new Spiralize closed contours option converts multiple passes around a closed contour or shape into a single spiralized motion. This improves cut consistency in a single lead in followed by a continuous cut around the part for multiple passes. This results in one single lead out move instead of multiple retracts which would break up the cut for every pass.

This is useful for replacing repetitive multi-cut linking moves with continuous toolpath motion.
