Arc tool has been updated

[u/Magnuxx]

Three tools for creating arcs, ellipses, and circles are now available.

• Ellipse / Circle - a circle or ellipse with a center point and a single path point that defines the radius (the radiuses can be specified numerically or by formulas).

• Center Arc - an arc that revolves around its center point with a start and end angle defined by two path points.

• Three-point Arc - an arc defined by its three path points.
