Add ISF Format Export

[torinmb]

Replace all uniforms with the ISF standard, so our SDFs can be dropped into other platforms like VDMX and Max MSP and have sliders / UI auto-generated.

Is there a js library for parsing this format? If so we could just replace our current method of passing a uniforms dictionary

[torinmb]

Yeah, I'm basically using my own version of ISF to store the uniforms right now, so I should just switch to ISF. Looks like there's a helper library: https://github.com/msfeldstein/interactive-shader-format-js
