(SArucoTracker): doesn't display marker if image components < 4

Marc SCHWEITZER requested to merge 453-sarucotracker-doesn-t-display-marker-if-image-components-4 into dev

What does this MR do?

Test the number of components of the input image before doing OpenCV conversion.

With this modification we can now handle both 3 and 4 components images.

How to test it?

Test with and without the modification in ExVideoTracking for example with opencv Grabber.

You can also test the TutoSimpleAR to confirm.
