Make minMarkerPerimeter and maxMarkerPerimeter user-configured for Multi+Aruco

Currently, the values for minMarkerPerimeter and maxMarkerPerimeter are hardcoded when the multicolormarker with code is used.

Code which does the hardcoding

    else if (recoMethod == RecognitionMethod::MultiColor)   // for usage of codemarker with MulticolorMarker
      {
        QRect rect(0,0, img.rows, img.cols);
        // from Aruco Documentation values 0 + 4 all info is considered (low performance issues expected due to small image size)
        minMarkerPerimeterRate = 0.02;
        maxMarkerPerimeterRate = 4.;
       }

The value should be assigned by the user, as it already is when directly using the codemarker.
