feat: Manage YTM/YouTube video/tracks in playlist

[IlIllIl]

Feature description

• Mark duplicates and dedupe
• Multi-select
• Sort by video title alphabetically (and reversed?)
• Sort by publisher alphabetically (and reversed?)
• Sort by publish time (and reversed?)
• Sort by view count (and reversed?)

Motivation

I've seen the API is simple, but no one has done it on third-party client? Only have some python scripts or chrome extensions, which are not so handy. Really need simple playlist management, but Google doesn't make such thing.
