Add support for Cloudflare Request Attributes #1
Conversation
Cloudflare workers now includes [Request Attributes](https://developers.cloudflare.com/workers/reference/request-attributes/). These attributes are accessible every request from the cf object. i.e: `request.cf`. This PR allows us to set and get the request attribute from `request.cf`. To set a cloudflare request attribute: ```js const request = new Request('https://example.com', {cf: {country: 'AUS'}}) ``` To access the request attribute: ```js request.cf ```

I think we need to be stricter about what is possible on the cf object otherwise the behaviour doesn't align with the Cloudflare implementation. My proposal here is that we drop any keys that are not defined in the controlling Cloudflare feature docs to ensure that if a key is set, it will remove it and cannot be asserted against. Without this, someone could any key to this object, test against it but not have it do anything within the worker environment.

Can we also update the name of this module to be something like |

Looking good, but I wonder if we could use Object.defineProperty instead to add the Cloudflare property? Perhaps a simple jest fetch wrapper?
It would be good to add a section to the docs/readme about the Cloudflare specific features we're adding.

Nitpick: country code should be AU.
