FEAT Implement Tree of Attacks with Pruning

[romanlutz]

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

The following paper describes a technique called Tree of Attacks with Pruning (TAP): https://arxiv.org/pdf/2312.02119.pdf
PyRIT doesn't currently support it.

Describe the solution you'd like

There's an existing repository with TAP code at https://github.com/RICommunity/TAP
We should either use this as inspiration or adapt it to work as an orchestrator in PyRIT (let's call it TreeOfAttacksOrchestrator)

This should include tests and descriptive docstrings.

Describe alternatives you've considered, if relevant
