Added MUX operation for HUD: Instead of adding some new detection steps to the autodetection loop (which would be another copy paste implementation) the detection loop has been reworked. Instead of having a several individual steps per sensor type the steps are now related to mux channels. A structure is used to identify the type which shall be handled during the uart channel iteration. This make the code better readable and maintanance easier.
