Butteraugli wasm source

[Ser-Gen]

Hello!
Could you publish sources of wasm version of Butteraugli or some build instructions please?
I have trying to made it by myself but no luck.

They made some speed improvements for Pik, looks like from one of pull request.

Finally got it!
github.com/pixhub-int/image-processing/tree/master/butteraugli

Сouple of differences
— Heatmap is generated in rgba
— Using code from PR for speed up. Looks like they use the same in Pik.
