[Add Lasso Tool/ Free selection tool for Vector Persona]

In a FB group someone posted how to do a lasso node selection on iPad. You need to touch the screen with 3 fingers, hold, then use Apple pencil to start lasso selection. Once done, lift pencil first, then lift fingers.

It sometimes needs a few tries with the three fingers to activate, but once activated your pencil move will start showing a selection area while being dragged.
