💡 Feature request: RSS filter like on Reddit

[foregroundprocess]

RSS feed contains all of the posts in a subreddit, even if I select TOP, or make a search.

On Reddit you do the search, apply the filters, like TOP of the week. And each result has its own URL, like
https://www.reddit.com/r/unpopularopinion/top/?t=week
Same on Redlib.

But Reddit also creates an RSS feed for such URL, like
https://www.reddit.com/r/unpopularopinion/top.rss?t=week

Can Relib behave in the same way? Currently RSS URL remains the same for a subreddit even if I set a filter.

For anyone looking to work on this: seems like the sort parameter isn't being parsed correctly around here:

redlib/src/subreddit.rs

Line 588 in bbe5f81

let sort = req.param("sort").unwrap_or_else(|| req.param("id").unwrap_or(post_sort));

Leading to the default case 'hot' being chosen at all times.
