Fetch actual raw streamable URLs from various radio-station, video & podcast websites.

Changes for 2.16 - 2023-08-24

• Added StreamFinder::Zeno for zeno.fm radio stations & podcasts.
• StreamFinder::Brighteon - Add "formats_by_channel" option keyed by albumartist. This needed b/c some video formats (ie. .m3u8) don't seem to work on some sites but are the only ones that work on others.
• StreamFinder:😛odchaser - Add "-notrim" option to trim trailing garbage off stream URLs.
• StreamFinder:😛odchaser - Fix sometimes fetching wrong stream on episode pages, and fix podcast pages not returning any episodes due to recent changes in their site (more stupid javascripting).
• StreamFinder:😛odcastAddict - Mark DEPRECIATED since they recently javascripted & crapped up their podcast pages making it now impossible to fetch a playlist or first episode from them (correct episode pages still seem to work for now, if you get them from your browser first).
