Web analytics

[jprochazk]

What

Part of #2966

• Enable analytics on the web with the same events as native viewer
  • Events have a wasm32-unknown-unknown target, and have the url set to the string value of window.location
• Expose set_email global function when running on the web
  • Used to identify Rerun employees in the same way as rerun analytics email <[email protected]>
• Disable analytics if the web viewer is running in the context of a notebook
  • To detect it, we set the notebook=1 query param on the iframe

Expose set_email global function when running on the web

We should document how to run this, and who should run this. rerun analytics email is currently documented here, so I guess it makes sense to document set_email in the same place (no need to make it public, even though it is hardly a secret)

Looks good! But we really need to limit what urls we send to analytics 😬

Yeah, I wasn't sure where exactly to put it. I updated the document.
