OpenEXR bumping its vendored OpenJPH to 0.33 broke our CI because the lossy encoder output changed slightly vs 0.32. This patch switches testsuite/openexr-compression's comparison strategy for j2k to make it less brittle: compare it against the original image with a threshold suited to lossy compression instead of against a stored reference, and drop ref/out-lj2k.exr.
