OP-1217 create new receiver module

This module includes all the receiver IO and parsing/failsafe
functionality of ManualControl, but does none of the interpretations in
regards to flight mode / actuator control or arming that was included in
the old ManualControl

In a second step the old ManualControl module needs to be adapted to do
only these ommitted things in a modular way - as a delayed callback
