Implements OCR-based conversion of PGS (Presentation Graphic Stream) subtitles to SRT format with automatic tool detection. Features: - Auto-detect Tesseract OCR from PATH or Subtitle Edit installations - Auto-detect MKVToolNix from standard install locations - Support multiple language codes (ISO 639-2/3, language names) - GUI checkbox to enable/disable OCR for PGS subtitles - Automatic cleanup of intermediate .sup files after conversion Dependencies: - pgsrip: PGS subtitle OCR engine - pytesseract: Tesseract OCR wrapper - babelfish: Language code handling - opencv-python, cleanit, trakit: Image/metadata processing Known limitation: This feature works when running from source (python -m fastflix) but not in PyInstaller-built executables due to subprocess environment issues with pgsrip. Users needing PGS OCR should run from source.
