Some impl. paper of Fant's algorithm: https://ieeexplore.ieee.org/document/5764000

Fant's original paper: https://ieeexplore.ieee.org/document/4056711

"The algorithm is complete in the sense that all the pixels of the input image under the map of the output image fully contribute to the output image."

Will use https://github.com/andrewekhalel/sewar as a reference implementation in python. And https://github.com/darosh/image-mse-js as something to build on for js code.

Current js-tests available here: https://joedf.github.io/ImgBeamer/tests/image_metrics/js-tests

• Metric calculation likely needs to update at when a full frame / last row is drawn...
• Add option to switch metrics?

Moved these to #36

Closing as more or less complete and relatively stable. Open a new issue, if further changes wanted/needed.
