Update dependencies and enhance CSV metadata handling

- Updated requirements.txt to specify minimum versions for PySide6, pyqtgraph, and numpy.
- Modified CSVFileMetadata class to include a new master_type attribute for improved metadata representation.
- Enhanced FileBrowser class to handle master_type in metadata saving and retrieval.
- Added a new method in FileBrowser for parsing CSV metadata, improving error handling and data extraction.
- Adjusted LocalSettingsModel to format code and change default reverseZWafer setting to False.
