Chromatic aberration filter as in G'MIC

I know there’s another FR and also the workaround(s), but it’s all a bit clumsy and not precise enough, especially if you have to deal with badly digitalised videos from VHS recordings.

G’MIC has a really nice and versatile tool to handle the problem for images, which I’ve been using a lot. It’d be great to have something similar in Shotcut.
