Supporting a Publishing use-case

[cinnamon-bun]

What if you want to publish some webpages via Earthstar? Here's a couple ways:

1. Get Earthstar support in Agregore browser by finishing earthstar-fetch. It specifies an URL scheme for viewing workspace document data in a browser.

2. (Easier) Add a new URL pattern to earthstar-pub which, in addition to syncing, can also just serve document content as regular HTTP responses. We could try to match the URL scheme from Earthstar-Fetch.

Number 2 is really nice -- you just spin up a pub, sync your data to it, and it acts as a web gateway for viewing webpages stored in your Earthstar documents. You could even embed some javascript in there and distribute whole Earthstar apps that way.

We also need #7 Invite-only workspaces so that people can read and help host the data without getting the ability to write to it.
