Update RangerMain and charging_station:

For all nodes of both files : use settings in order to have generic code for each Ranger and charging_station

For RABs : Improve communication protocol in order to can recover only true data packets with pseudo tx timeslot from the Rangers

For Ranger-Neuil : Add new function interfaces, Init the pupil and eyelids at the begining, essentially to try to unstick magnets without losing them
For Ranger-Main : Filter the rear panel touches : none can be detected for the moment
