[feature] Atom feed generator

[ehmry]

Is your feature request related to a problem ?

I want to embed a lists of posts from a user in a webpage in declarative way.

The only way that I've found to do this so far is to process an RSS feed using XSLT into XHTML, but the post content is opaque CDATA and cannot be parsed back into HTML by a browser, so formatting nodes like <p> and <br> are uninterpreted.

Describe the solution you'd like.

If I could get an Atom feed from GoTosocial with posts as XHTML atom:content nodes then I can inject posts into pages.

Describe alternatives you've considered.

I will not consider alternatives involving JSON, "java" "script", or running an additional server-side process.

Additional context.
