Feature request: accept brotli encoding

[Seirdy]

Full-text feeds can get large. My site's feed is 366kb gzip-compressed, and 288kb brotli-compressed. The Brotli feed saves 78kb, or 27%, and the gap will widen as my feed grows in size.

Feeds get fetched very frequently: mine gets fetched over 1000 times per day, and others' get fetched orders of magnitude more often. For some blogs it can be one of the major sources of bandwidth. Users often subscribe to hundreds of feeds at a time, so savings pile up on both ends.

Hi!

Thanks for the idea.

The support for brotli is in the version 1.5.5 of the backend (gh-203) and has already on https://feed.fun

I'll also add the support for the zstd compression in the future (gh-204) — it requires a bit more work.

I'll be grateful if you could test it and let me know if it works for you.
