Challenge aido-LFV_multi-sim-validation

`LFV_multi`
Control multiple Duckiebots
	In this variation of the lane following challenge, your agent is embodied in multiple robots. Avoid the crashes with different versions of yourself. See the documentation for more details.

These are the metrics defined:

Survival time - survival_time_median: This is the median survival time. The simulation is terminated when the car goes outside of the road or it crashes with an obstacle or pedestrian.
Major infractions - in-drivable-lane_median: This is the median of the time spent outside of the drivable zones. For example this penalizes driving in the wrong lane.
Traveled distance - driven_lanedir_consec_median: This is the median distance traveled, along a lane. (That is, going in circles will not make this metric increase.)

This is discretized to tiles.
Lateral deviation - deviation-center-line_median: This is the median lateral deviation from the center line.
