Option to run @helia/http as Rapide

[meandavejustice]

After we get #289 completed. We should look into a version/option to run as Rapide.

I'll need to spend a bit more time thinking about this and familiarizing myself with Rapide, but initial thoughts are that each gateways gets a service worker (worker thread if Nodejs). I'm assuming there is some library that provides an api which will let us treat them the same.
