Feature: Langchain Memory

[NicoSzela]

Hey there,

Great job on this library, it's been really useful for my needs. However, I've hit a use case that would need langchain memory, which is not implemented (yet?).

My application needs to translate user input into search parameters for database filtering. But, because the translation can sometimes be inaccurate, I'd like to give users the ability to manually edit these search parameters as they wish. This could be done either within the app's UI and/or directly using natural language in a chat box. Basically, users should be able to tweak the output (the list of search parameters) until they're satisfied with it, which requires langchain memory.

I think this could be a really cool feature that would broaden the possible applications of the library.

What do you think?

Thanks!
