Add UIQI metric

Universal Image Quality Index (UIQI) is another full-reference method for quality assessment. https://ece.uwaterloo.ca/~z70wang/publications/uqi.html

I abandoned implementing UIQI. The reasons is that it is basically SSIM but it does not work for some special cases of images (division by zero may occur). One should just use SSIM instead.
