Converted to exeldro/OBS-shaderfilter

[kryztoval]

I converted the shadertoy version of the shader to a shader filter for exeldro's obs-shaderfilter and it works great!

I've also converted it into obs-shaderfilter and made a PR there:
exeldro/obs-shaderfilter#68

For those looking for the converted shader that I've made, you can try this:
smart_denoise.shader
