Construct a working robotic vehicle from many parts.
Each part runs as a job in the Vehicle loop, calling either
it's run or run_threaded method depending on the constructor flag `threaded`.
All parts are updated one after another at the framerate given in
cfg.DRIVE_LOOP_HZ assuming each part finishes processing in a timely manner.
Parts may have named outputs and inputs. The framework handles passing named outputs
to parts requesting the same named input.
