EZT 4.6 Corrected Engines: Scientifically Corrected Implementation of Extended Zero Theory for Black Hole Analysis

A scientifically corrected Python implementation of the EZT 4.6 theoretical framework for analyzing gravitational wave echoes and estimating black hole spin parameters. This version corrects critical errors in the original implementation, particularly in the Kerr spin estimator which incorrectly used a linear approximation instead of proper Kerr geometry equations from Bardeen, Press & Teukolsky (1972).
