4.0

Improvements

• Added "library" to locally save and load tracks without using the YouTube API. Now you can use Beatnik entirely "offline" after saving items to your library.
  • New caching strategy that locally saves metadata.
  • Playing an unsaved track always streams, playing a saved track always plays from cache.
• Support YouTube cookies for videos that require authentication/age gate/etc.
• Various optimizations to make most operations run smoother

Breaking changes
