feat: Enhance activity API feat: Enhance sleep data import functionality with support for multiple CSV formats and improved data parsing

- Added functions to handle Apple Health sleep data in both segment and summary formats.
- Implemented robust error handling for date parsing and data conversion.
- Updated documentation to reflect new CSV format support and data aggregation logic.
- Bumped version in version.py to reflect the changes in the activity module.
