Any parameters given in ¶ms=... are appended to /watch URLs. This
allows e.g. passing &raw=1&listen=1 to a playlist of music and use an
rss reader like newsboat as a media player, like so:
https://invidio.us/feed/playlist/XXX?params=%26raw%3D1%listen%3D1
All three feeds--channels, playlists, subscriptions--are supported.
