feat(blackbox): the cab panel as fits the vehicle, every switch the driver worked in the events

- The rest of the cab record is read when written: what drives the
  vehicle, the doors' permits and departure signal, the brakes of the
  whole train, a diesel's oil and temperatures, the cruise control and
  the rest.
- Cab panel: the traction as fits what drives the vehicle (voltage and
  current of an electric one; revolutions, oil pressure and temperatures
  of a diesel; clutch or torque converter of a mechanical or hydraulic
  one; nothing for a draisine), the equalizing reservoir, the main
  reservoir pipe and the most braked cylinder of the train, the brakes'
  setting and mode, a group of the doors, the pumps of a diesel where an
  electric vehicle has its pantographs, the hand brake, the releaser, the
  horn's tone, the radio's channel, the integrated handle of a unit.
- Events: every switch on and off, doors opened and closed, the departure
  signal, the hand brake, the brakes' setting, the radio channel, the
  cruise control's speed; moving with the doors open and an overheating
  engine as faults.
- A vehicle with no lamps at an end (a draisine) is not judged on its
  lights, and one which never had a voltage shows none.
