feature request: support for Atom Entry Documents

[hober]

I have an aging website whose backing store is a whole pile of Atom Entry Documents, and I'd like to replace the Python script that processes them with a Swift program. But it doesn't look like FeedKit supports these documents; I get a feedNotFound error when I try to parse one.

Given the relative unpopularity of Atom at this point, I'm not sure it would make sense to put development effort into official support for entry documents. However, depending on the specifics, it looks like direct support might not be too hard to work around.

Can you upload a couple of the entry documents you're working with? Do you generate these documents (or get them from a source with consistent formatting), or do they come in from a variety of sources?
