Support OEmbed

[enjikaka]

General support over all clients for OEmbed would be nice. It would give the chat possibility to present players for TIDAL, Spotify, Apple Music and similar services when users share links to songs on these platforms. OEmbed is also used for other services.

To reduce clutter this should probably be behind an option flag too.

Should be fairly straight forward to implement. Links that are posted in chat need to be crawled, checking for a <link rel="alternate" type="application/json+oembed" href="..."> tag, which points to an URL where you can fetch information on how to embed it. Example. Most often it's an iframe with some sizing information.
