Remove field "pedRadius" from PedestrianOverlapProcessor
The field pedRadius should be removed from the PedestrianOverlapProcessor. This information is present in the SimulationState and it should be depending on the actual pedestrian's radius (for both pedestrians) instead of being a constant. At the moment, in every updateStep, the radius is set to the current radius of the pedestrian but this is only a quick fix. Instead, for each comparison the radius of both pedestrians should be considered. This part is mainly thought for future application in which pedestrians might not all have the same radius.
@hm-schuhba1 : The Migration Assistant needs to be adapted for the change.
