Sketcher: New Feature: Hyperbola/ArcOfHyperbola

===============================================

- ArcOfHyperbola creation method
- Solver representation (undefined moving)
- SketchObjectPyImp (here we still miss the Part->Partdesign conversion)
- Sketch validation for hyperbola
- Hyperbola creation method: shows the "proof of concept", but it is very buggy!!

Notes:
- Missing icons, probably missing geo normal curve implementation - rebasing -
- Fixes to adapt Hyperbola to Derivector implementation and make it compile
