Newpipe: [Proposal/Feedback] Reorganisation/recategorisation of Settings

[opusforlife2]

This issue is to collect ideas from the community on how to better organise various settings in the app. For example, #3184 does this for two such settings.

I am in favour of adding a "fine-tuning" settings section, inside which we could add all of the settings people ask for, and they wouldn't be cluttering the ui and reducing accessibility.

[opusforlife2]

I think it is also worth separating and demarcating service-specific settings, because an increasing number of services would result in a jumble of settings. For example, download resolutions are different between Youtube, MediaCCC and Peertube, both for video and audio, yet the existing setting caters only to Youtube.

The existing setting shuld do the same for every service :thinking:

MediaCCC, for example, has a weird resolution of 576p, and Peertube has 300p. Soundcloud currently has only one bit rate for MP3's, but when it gets Opus support, then we'll need a bit rate selector for that. Plus I think we should have a default bit rate selector for Youtube audio playback as well.

Feed-related settings could be grouped into their own menu, when things like auto-refresh and pull to refresh are added.
