demo: evaluate wasm in the browser

[srenatus]

✨ opa-wasm.glitch.me ✨

It's a small demonstration page, that allows you to compile Rego policies to Wasm and evaluate the Wasm module in the browser

With the network tab in your browsers dev tools, you can see that the evaluation is happening purely client-side.

Also useful for debugging

Since OPA's Wasm modules are run in the browser, you can use Chrome's DevTools to inspect and debug them:

See https://developer.chrome.com/blog/wasm-debugging-2020/#memory-inspector for starters.
