Feature request: Add Fetch API adapter aka "Web Platform support"

[esamattis]

Eg. support for the Request and Response objects specified in the Fetch Standard. It would allow deploying to Remix routes for example.

Unfortunately I don't have the time to work an a proper PR but I created a userland adapter that can be used with Remix:

The implementation is probably very naive but at least it is some short of starting point.

Yes, I actually started this refactoring once, should be picked up for sure!
