Validation with tail-estimation

[mu373]

Updates

• Updated random seed implementation to that of tail-estimation
• Wrote tests to validate tailestim results to tail-estimation. See tests/test_tailestimation_validation.py.
  • Validates numerical equivalence for each estimator (Hill, Moments, Kernel, Pickands)
  • Comprehensive multi-dataset (CAIDA_KONECT, Libimseti_in_KONECT, Pareto, and complete graph) validation across all estimators
  • Reproducibility tests with various random seeds
  • Plot data comparison (PDF, CCDF, bootstrap AMSE)
• Added Jupyter notebook for interactive vaildation

The tests can be executed with the following command:

pytest tests/test_tailestimation_validation.py -v
