- Modified ProcessData class to utilize source generation context for Description deserialization.
- Renamed RowSourceGenerationContext to QS408MRowSourceGenerationContext for clarity.
- Updated Run class to use QS408MRunSourceGenerationContext for serialization.
- Enhanced Description class with source generation attributes.
- Refactored FileRead class to use source generation context for Description deserialization.
- Added new methods in ProcessDataStandardFormat for JSON element array extraction.
