Add enhanced configuration templates for adaptive I/O features

- Introduced a comprehensive configuration template (config-adaptive.toml) for adaptive I/O, enabling improved upload/download dual stack with various performance optimizations, security settings, and network resilience features.
- Created a test configuration template (test-config.toml) mirroring the adaptive configuration for testing purposes.
- Added a simple test configuration (test-simple-config.toml) for basic adaptive features testing with essential parameters.
- Included an empty Jupyter notebook (xep0363_analysis.ipynb) for future analysis related to XEP-0363.
