UNICADOworkflow: - add functionality to bridge constraint_analysis in RFD mode
- add script and joiner component to workflow to bridge constraint_analysis in RFD mode
- change path of center_of_gravity in estimate_design_residuels.py to check CoG at maximum take-off mass
Attention: only mode_0 / mode_1 / mode_3 / mode_4 could be tested -> no errors occurred -> behavior is like expected
mode_2 could not tested correctly, because wing_design code not run in RFD mode
