To reduce complexity, and make it easier to add more images and tests, the images in the `test-data` repository should be merged with the main repository. Furthermore, we can remove a lot of the subprocess work in the image_testing.py file, as we no longer need to have it interact with git. The images are not the same. Images were regenerated with Qt6, and now have proper big and little endian handling thanks to @pijyoi Second commit is a slightly modified variant of 2e135ab282d6007b34a3854921be54d0e9efb241 authored by @pijyoi it is to convert qimages to RGBA8888 for testing. Image files were regenerated images for the big/little handling Fixed issue with bogus test from test_NonUniformImage and generated a new image
