RSS feed dates not parseable according to spec

[samhh]

Hi there!

I noticed that openring and the underlying Go RSS library are unable to parse at least the post pubDate fields in your RSS feed. I think this is because it's not spec-compliant with RFC 822.

For reference this feed is parsed, but I don't know if it's necessarily spec-compliant: https://blog.ploeh.dk/rss.xml

Relevant line probably here: https://github.com/lexi-lambda/lexi-lambda.github.io/blob/source/blog/build/render/feed.rkt#L44

I suppose it needs something similar to that above in the Atom code chunk: (published ,(post-date->rfc-3339-datetime date))

Cheers!
