Metrics on AttackSuccessRate
================================
This module contains the implementation of the AttackSuccessRate metric,
which is designed to evaluate the effectiveness of jailbreak attacks in a dataset.
It calculates the number of successful and failed attacks, and computes the overall
attack success rate.
