Add TagManagerGUI for enhanced tag management in PhotoTagger

This commit introduces the TagManagerGUI class, which provides a comprehensive interface for managing photo tags within the PhotoTagger application. The new GUI preserves the legacy functionality while integrating into the refactored architecture, allowing users to add, edit, and delete tags efficiently. The PhotoTagger class is updated to utilize this new feature, streamlining the tag management process. Additionally, relevant documentation in the README has been updated to reflect these changes and provide usage instructions.
