Apply code formatting and linting fixes

- Applied isort to organize imports across all Python files
- Applied black to standardize code formatting
- Fixed import organization and code style
- All tests continue to pass (131 passed, 1 skipped)
- Core functionality verified working after cleanup
- Documentation builds successfully

Note: Some flake8 warnings remain but are style-related and don't affect functionality.
These can be addressed in future if needed.

 Calculate dynamic correlations
 =============================
 
-This example demonstrates how to calculate dynamic correlations between two 
-timeseries datasets using the `wcorr` function with different kernel functions.
-
-The `wcorr` function computes weighted correlations between two datasets using
-a kernel-based approach, allowing you to see how correlations change over time.
+In this example, we calculate dynamic correlations
