[rdheekonda]

Description

1. Added DuckDB database functionality into PyRIT as primary memory storage.
2. Deprecated FileMemory module.
3. Restructured memory models to utilize SQLAlchemy for schema detection.
4. Implemented data export functionality default to JSON format
5. Added DuckDB with update functionalities, adaptable to new attack techniques.
6. Moved analytics functions from core memory interface to analytics sub package.
7. Updated demo\code for memory pointing to DuckDB memory.
8. To release database resources, we need to manually invoke dispose_engine at the end of the Jupyter notebook, as automatic exit functions like atexit or __del__ are not reliably triggered by the Jupyter process.
9. Added cleaning up DB resources logic to base orchestrator class and used in demo notebooks
10. Clean up FileMemory references in the core repo.
11. Fixed bug in prompt_target_text, class variable declared as _memory but instance variable is defined as self.memory

This is biiiig, so tough to tell smaller issues. But imo let's get it in and tweak it, I think the overall design is really good
