rendering the mandelbrot set in webgpu
https://webgpu-mandelbrot.netlify.app
as of writing only Chrome supports WebGPU, so that's the only browser where this'll work
because webgpu is limited to float32, after a certain scale zooming stops working.
to address this, i need to emulate float64 support using float32's, i just haven't gotten around to it yet.
clone the repo, with node.js/npm do npm i, then npm start
