feat(utils): add utility function to move vehicle reference position

[kschrab]

Description

• Simulators may have different reference positions of vehicles, e.g. SUMO points on center of front bumper, while Carla and PHABMACS refer to the center of the vehicle's bounding box.
• A later goal should be to generalize this across MOSAIC, so simulators may have to adjust the positions they put into VehicleData objects.
• As a first step, this MR provides utility functions to conveniently convert from "front bumper" to "bb center" and vice versa for the 2D-case.
