feat: Implement data analysis and code execution utilities

- Added data_analyzer.py for comprehensive data analysis with templates for summary, correlation, distribution, and custom analysis.
- Integrated logging for tracking analysis processes and errors.
- Included package installation functionality for required libraries.
- Developed python_executor.py to safely execute user-provided Python code with sanitization and timeout features.
- Implemented security measures to prevent unsafe code execution.
- Enhanced output handling to capture visualizations and standard output.
