Artificial Traffic Groundradar

Current development of a groundradar for AI (Artificial Traffic). Previously the AI code would check collision based on routes, which involved multiple Djikstras each few seconds and not helping with parallel/overlapping routes like with pushback. In order to get the code working multiple bugs had to be fixed and some refactoring (enums). It's still WIP and feedback is welcome. SPDX headers are not all fixed.
