Implement a unified export system for extracting data from parsed files:
ExportManager (singleton):
- Centralized export handling for all content types
- Content type detection (image, audio, video, text, binary)
- Batch export support with progress tracking
Format-specific export dialogs:
- ImageExportDialog: PNG, JPEG, BMP, TGA with quality options
- AudioExportDialog: WAV, MP3, OGG with FFmpeg integration
- BinaryExportDialog: Raw data export with optional decompression
- BatchExportDialog: Recursive export with filtering options
- Base ExportDialog class for common functionality
Settings additions:
- FFmpeg path configuration with auto-detection
- Search common install locations and PATH
