- add py routine makeLeader(points)

* [TD]add leader conversion utility

* [TD]Set Leader RotateWithView default to true

* [TD]fix intersection vertex position

* [TD]add CosmeticEdge::makeLineFromCanonicalPoints

* [TD]fix 2 Extension tools

- positioning in DrawCosmeticCircle
- mishandling of points in execLineParallelPerpendicular

* [TD]Remove duplicate constexpr

* [TD]fix 2x Cosmetic arc tools

* [TD]refactor LineFormat out of Cosmetic

* [TD]move cosmetic appearance settings to LineFormat

* [TD]remove 2 unused methods
