Replace resource.js with ouroboros

[gabesullice]

Ouroboros was based on this project's resource.js file, but now ouroboros has a better API and test suite.

We should replace the resource.js file and any related code with a dependency on the ouroboros library.

This will ensure that the data in user's client-side code will exactly match the data structure in their server-side code if they're doing SSR with Applura.

For a starting point, see

import parse from "./resource.js";
