Pull Request Summary

[debpal]

This pull request includes:

• Introduced Calibration class to enable model parameter calibration.
• Added hru_stats_from_daily_simulation method in the DataManager class to compute monthly and yearly statistical summaries from daily time series data.
• Renamed types.py to newtype.py to avoid conflicts with Python’s built-in types module, which caused import issues.
• Moved repetitive functions into utils.py and validators.py to improve code reusability.
• Added cpu.py module to support running simulations on a separate CPU. This method could not be placed in utils.py due to import dependencies with the TxtinoutReader class.
• Removed API documentation for newtype.py, as detailed explanations are already provided in other relevant classes to prevent user confusion.
• Updated and refined documentation for consistency and clarity.
• Added pymoo dependency for multi-objective optimization support during model calibration.
