Description

Use the Lark grammar feature of the OpenAIResponseTarget to create a beam search for PyRIT. This is a single turn attack, where a collection of candidate responses (the beams) are maintained. On each iteration, the model's response is allowed to extend a little for each beam. The beams are scored, with the worst performing ones discarded, and replaced with copies of higher scoring beams.

Tests and Documentation

Have basic unit tests of the classes added, but since this requires features only currently in the OpenAIResponseTarget there didn't seem much point in mocking that. There is a notebook which runs everything E2E.
