feat(grafast/grafserv/src/servers/deno.ts): add deno server

[nestarz]

A first stop to be used in Deno.

(Just a note to say thank you for submitting this. I'm currently super busy preparing for GraphQLConf so I might not get around to properly evaluating this until October - not least because I've not really used Deno before and will have to familiarize myself with it before taking on the maintenance of this adaptor.)

[benjie]

This looks great; I love how simple it is!

[benjie]

That's as much as I can do right now; please:

1. Solve the issue so that TypeScript running on Node doesn't crash (install the Deno types?)
2. Add a page to the Grafast documentation like this one: https://github.com/benjie/crystal/blob/main/grafast/website/grafserv/servers/fastify.md (Ideally better!)

[nestarz]

Thanks for your review ! I will add the required changes you mention asap. Thanks for your work.

[benjie]

(Please be aware this PR should now be raised against https://github.com/graphile/crystal instead ❤️)

[benjie]

Please re-open this against the above repo. I've pushed a few more commits but I've literally no idea how to go about running this locally - it seems that Deno doesn't support running local code in npm compatibility mode? denoland/deno#18474 Without that, I can't be certain it works, so that's the first thing to solve.

[nestarz]

Noted ! Thanks for your work @benjie

Incidentally if you need help doing the git-fu to move this over:

1. Pull down these commits into your local clone (git pull --rebase)
2. Fork the graphile/crystal repo via GitHub interface
3. Change the remote for your existing local clone to point at the new repository (git remote set-url origin [email protected]:nestarz/<new repo name here>.git)
4. git push -u origin patch-1

Then raise a PR :)
