Draft: warn for unsupported objects

Grantrequested to merge
1-unsupported-warning into main

Closes #1

As fediverse.ooo is client-only, we might run into issues w/ cors being unable to request object data

Object type either needs to be provided in the original URL or by requesting the object data directly

Current changes add capabilities defined in the PROVIDERS.ts

There are two main software types, one for communities (forum style), and one for individuals (mastodon, misskey)

Peertube is the exception, with it not following either, and not being able to render either
