With an image or, for example, 4 columns of 5 QR codes with the same module size, groupMarks will find many possible combinations of markers, as it only checks:

• that the module size are compatible (OK)
• that the markers form a rectangle triangle (OK with codes ordered in rows and/or columns)

This results in a lot of memory used (too many images are extracted), and a lot of bad results.

outputPrefix must be removed from the example for it to work.

When the fourth corner of the box is calculated, groupMarks() should check that is in the image, and drop the result if it is not.
