LaneCrossingCalculator tried to create LaneMarking objects without check if the respective information object exists at all.
Description
Running manual_control.py on a custom made map showed segfaults. Debugging lead to a nullptr access on the not existing information from the map. OpenDRIVE maps are valid even without lane marking information (or with a reduced set of it). This change prevents from the segfault an just returns an empty list of markings.
