Added ExifTool integration to support 300+ file formats with improved performance and unified API for metadata operations. Changes: - Added PyExifTool>=0.5.6 to requirements.txt - Created comprehensive ExifTool setup guide (docs/EXIFTOOL_SETUP.md) - Created ExifToolExtractor for reading metadata from images/video/PDF - Created ExifToolUpdater for writing metadata to images/video/PDF - Updated README with ExifTool installation instructions ExifTool Benefits: - Unified API for images, videos, PDFs (vs 5+ separate libraries) - Support for 300+ formats (HEIC, RAW, MKV, and more) - 10-60x faster batch operations with stay_open mode - Better PDF metadata writing (current pypdf is read-only) - Battle-tested tool with 20+ years of development Architecture: - Hybrid approach: ExifTool for images/video/PDF, Python libs for Office - Graceful fallback if ExifTool not installed - Automatic detection on startup with helpful messages - Tag mapping from ExifTool tags to standard fields (title/subject/keywords) Implementation follows existing extractor/updater patterns for consistency.
