Coding the right event horizon for Kerr & Kerr-Newman space-time

See original GitHub issue

🐞 Problem As of now, in calculation of time-like trajectory in Kerr metric stops and raises a warning on reaching schwarzschild radius. But event horizon in kerr spacetime is smaller than schwarzschild radius. But the exact values need to be researched.

🎯 Goal

Research about the problem and specify the correct radius after which computation should stop in metric/kerr.py.
Kerr
Kerr-Newman
