This PR adds data for testing of chromatic aberration calibration and correction.
It includes a calibration pattern made from many black discs arranged in a rectangle which is printed out on A3 paper, and a photo is taken with a camera with an open aperture. On the camera, I disabled all kinds of existing chromatic aberration corrections and denoising. My camera can only save in .cr2 or .jpg, but I converted the image taken to .png.
Also, this PR includes the sample calibration data which the calibration procedure should output when using the supplied photo as input.
TODO: add some photos taken with the same camera with obvious chromatic aberration
