Enhance metadata management in PLib video library manager by introducing new label handling features. Update LibraryDataKind to include Tags, Performers, Studios, and Collections, allowing for more granular data clearing options. Revise LibraryService to support label management during data resets, ensuring proper handling of user-added metadata. Update README.md to reflect these changes and clarify the implications of data clearing operations.
