[quickview] Add test |openQuickViewImageRawWithOrientation|

Now that piexloader supports using a RAW image's "thumbnail", add a
Quick View test using a RAW .NEF file containing only a "thumbnail"
image. Because the image has an orientation in its metadata, it should
render rotated 90 degrees clockwise.

Also test that the dimensions shown in the metadata box reflect
the rendered orientation of the test image.
