- Add enablePanelDetection, libraryType, formatGroup state
- Add panelDetector instance for dynamic loading
- Update initReader to accept and process configuration
- Conditionally load panel detection only when enabled
- Use dynamic import for foliate-js/panel-detection.js
- Add error handling for panel detection loading
