Is your feature request related to a problem? Please describe.

The suffix attack from https://arxiv.org/pdf/2307.15043.pdf is not yet supported by PyRIT. More examples are on their webpage https://llm-attacks.org/

Describe the solution you'd like

They have code on GitHub at https://github.com/llm-attacks/llm-attacks
It should be used as inspiration or as a starting point and adapted to become an orchestrator in PyRIT.

This should include tests and descriptive docstrings.
 

Describe alternatives you've considered, if relevant
