Crash in Delaunay Triangulation with specific input geometry

[Ozaq]

The following geometry triggers a crash in DTriangulation.cpp:33

geometry.txt

[Ozaq]

J1_w0_0 and J1_w1_0 polygons in geometry.txt are CW oriented while the other polygons are CCW oriented. Creating a union from those polygons trips up CGAL.

To address this issue:

• Update doc: All polygons that jupedsim consumes have to be 'simple'
• Update doc AND implementation: CW and CCW ordered polygons are accepted (polygons will be reversed internally where required)
• Additional input validation (check for simple) is added where appropriate

Should be fixed on SUMO-Integration
