Include demos / examples that run in the browser

We should have some demos / examples that run in the browser on the web.

I came across this, maybe it has some boilerplate that would make writing such an example easier?

Yeah, I the blog post code uses wgpu as well. Someone needs to figure out all the right invocations to build everything for the web and then embed...all the dependencies support it. But it is a bit weird as it won't be running spirv, it will be running spirv translated to wgsl. Good enough for a demo though!
