Add README.md

For the last year I had hoped to create an issue detailing my steps to get this working. Since that didn't happen, and I am forgetting the details, I will put some info here that could help a person get started.

First, I just re-found David's blog post about this. This could be included in the module's description and/or README. https://davidwbarratt.com/node/49

1. Besides installing this module on your Drupal site, you will need to deploy this Cloudflare worker code in Cloudflare. https://github.com/davidbarratt/drupal-edge. Fork it, clone to local, run npm install, npm run build, and npm run deploy.
2. Go into Cloudflare and bind a route to the worker. https://developers.cloudflare.com/workers/configuration/routing/routes. To match all routes, *DOMAIN.com/*
3. (I may have needed to set up Wrangler on my local?
4. (I believe I installed the Purge and Cloudflare modules and enabled the Purge Core tags queuer and Cloudflare Worker Purge submodules.)
5. Under the Purge UI in Drupal, add your Cloudflare worker as a layer of cache invalidation, for the URL: https://DOMAIN.com/.cloudflare/purge

I needed to debug issues. Drupal core contact forms broke page caching. A viewsreference field 🐛 Viewsreference embeds Views without cache, breaking Dynamic page cache Fixed was breaking page caching. I still had issues where I needed to either clear Drupal or Cloudflare cache when updating content, which I did not troubleshoot because it is not a heavily-edited site.

Hopefully these notes can help someone.

Update: davidwbarratt.com is currently down :/

Yeah sorry about that. Something on Azure is borken so I'm migrating back to my Pi which is cheaper anyways.
