Fix Samsung NX gen 2.5 (NX300/NX30/NX2000/EK-GN120) cropbox [1]

[1] Samsung seems to place the sensor asymetrically in the camera
body, where the body crops off a fairly large chunk of the left
side of the sensor. So we adjust the cropbox so the exact centre
of the image remains the same as the camera JPEG output, then we
grow the camera crow according to a 3:2 aspect ratio and stop
before we start including garbage pixels.
I've already fixed this for the gen 1 (NX100, etc) cameras, and
now for gen 2.5 (NX300, etc), this leaves gen 2 (NX200, etc)
cameras, for which I don't have any usable samples yet.
Samsung NX 2nd gen centered cropboxes

it seems unlike the 1st gen and 2.5nd gen, the 2nd gen Samsung NX
sensors do not leave room for a 3:2 cropbox properly centered without
hitting garbage pixels beyond the vendor defined resolution.
