2.9.0

feat:

• opt-in aggregation playlists
• log the number of playlists created by playlist_builder
• config options for minimum track count for playlist_builder
• improve config repr

refactor

• BaseConfig now has package-level config objects defined within it (i.e. the right way) instead of merging them together at runtime
• Config keys are lower-case now instead of upper-case
• Config keys reflect this nesting instead of being flattened -- e.g. config.sync.user instead of config.user
• Because of this refactor, there are changes necessary to avoid circular imports...for e.g.:
  • The __repr__ function for config objects has been factored out into a new BaseConfigFormatter class
  • PLATFORM_REGISTRY has been factored into its own module
• Because the parent config object is now being passed around, instead of package-specific config objects, dumb things like having artist_first defined as a global option are no longer necessary (this is now config.sync.artist_first)
• A few changes have been made in order to clean up the warnings when running pytest
• The root of the director has been cleaned up a little bit
