Add a pixel test for JPX images with mismatched color spaces
Add a pixel test that contains 6 JPX images on a gray background. Each
image's color space type doesn't match the "/ColorSpace" entry in their
image object.
Currently these images can either cause crash or be rendered
incorrectly. The correct expectation is a gray background and none of
the images should be rendered.
