feat: fetch adapter

[lucasthevenet]

Closes #188

I'm not really sure if my approach is really the best way to implement this adapter.

In order to use the existing node http handler, I "mocked" the request and response objects to make them compatible with the Fetch API.

A better approach might be to implement a new base http handler (like the one in trpc).
That way we have a little more flexibility in terms of what we can pass as a request object.

Though it may not be worth the trouble since the approach I took does in fact work (however hacky it may be).

Open to any comments or suggestions on how we can improve this.

Not a bad approach for the time being 👍

The core of this package is currently directly coupled to node, I'd like to spend some time to address this in the future. Probably need a chat with @juliusmarminge to think about how best to publish this library so that you only rely on the required dependencies of your specific adapter.

+1 for the fetch adapter.

Hi @lucasthevenet Thanks for your work on this! I copied src/adapters/fetch.ts into my project and it worked locally. When I deployed it to Vercel, I got the following error when I hit the API:

TypeError: N.hasOwnProperty is not a function

Not sure what's different over there. Anyway, thanks for your work and I will investigate further :)

@lucasthevenet I think you forgot a workspaces for a full working PR. Overall, it is working well.

Hey everyone, sorry I haven't had much time to continue this PR lately. I think with the last fix for the example everything should be working now.

Ripped out src/adapters/fetch.ts and tested it on my very small project. So far it seems to function well both locally and in production (deployed with Vercel).

Would be really cool if this can be merged.
