Subtitle cleaning options

[Jeremy80g]

Tdarr does not currently handle subtitles well, and there appears to be ongoing issues with legacy plugins.

While it would detract from the simplification you are perusing, one existing option is to use the modified 'ffmpegCommandRemoveStreamByProperty' flow plugin as modified by @UnknownWitcher and described in https://github.com/HaveAGitGat/Tdarr_Plugins/issues/562
(Plugin attached with minor updates for compilation and renamed (js) extension. index.txt )

UnknownWitcher's modified version is preferred due to:

• Filtering by stream type.
• Fixed 'not _include' issues as raised in Tdarr #562

Flow '2 - Prep' can then be updated to include several subtitle cleaning options including:

• Prep & Clean - Clean Subtitles - Language ⏳
  Remove subtitle streams which are not included in the library variable
• Prep & Clean - Clean Subtitles - Codec ⏳
  Remove specific subtitle codec types. (e.g. PGS)
• Prep & Clean - Clean Subtitles - Title ⏳
  Remove commentary or descriptive subtitles

Example Library Variables:

clean_subs = true
subtitle_language = und, en, eng
subtitle_codec = PGS,ass,ssa
subtitle_title = comment,director,description,sdh

Thanks for the info and for taking the time to put this together! This will be helpful when I tackle subtitles. Yes, I agree they aren't handled well right now, pretty much the reason I'm skipping them right now.

I'll review this in more detail by the end of the week!
