Passing Pydantic models into nanobind

[andy-bell101]

Just wondering how best to achieve this. I want to use pydantic in Python then get C++ to do the heavy lifting. It seems like the simplest way would be to turn my parsed model into a dictionary via model_dump() then in C++ convert that into the nested structs. But then I have to maintain the model in two different places. Is there a better way?
