Adjust method: MultiColorMarker-with-ArucoMarker

If peds tilt their head a lot, peds are not recognized anymore.

Assumption: When smaller image around head (cropRect) is handed over to indCodeMarker() function, the code itself is not complete/cutt off. Therefore no pet is recognized and the trajectory interupted.
