Feature description

Some RSS feeds only include a small snippet of the article, or sometimes nothing at all. I've used other RSS readers that automatically extract the text of articles, usually on a feed-by-feed basis. It would be great to see this in russ as it really helps for offline use.

I'd suggest rust-html2text as it's built in Rust, is actively developed, and it is built on Servo which is under active development again.

Upon further reflection, this could probably just be done as a scripted post-processing step, which leads me to wonder if (as an alternative) russ could just include a way to run a post-processing command for a given feed. I will open a different issue for that.
