Replace foraging_sessions with local code

Currently this entire acorn is built by just taking the data from the pickle file stored by Han's code. I think this is analysis framework output so it's probably safe to do this, but we should find out more about how this works.

Han seems to have already run an LLM to do this in his own architecture. We can port the code over here https://github.com/AllenNeuralDynamics/aind-dynamic-foraging-database
