videocompare: Add support for new algoritm
This seems like a good addition to the set of frame/image comparison algorithms: https://github.com/alt-text-org/image-match-rs
An implementation of the image matching algorithm described in An Image Signature For Any Kind Of Image by H. Chi Wong, Marshall Bern, and David Goldberg . The algorithm is designed to detect nearly identical images, not images with the same conceptual content.
