Very nice! As I understand this will allow me to implement a postgre based chat message history, which I attempted in #186

exactly! 😄 , you just define the store and pass it down to the buffer, it could be anything (psql or any other).

@tmc Can we add option.WithTokenLimit() or something of the kind here? I know python lib has TokenBuffer class to flush to chat msgs that overflow the token size for a model. Not sure if we need an entirely new buffer for that, so we might consider it... cc @FluffyKebab

I will see when I grab time, to add the token limit, like they have in the python lib, maybe we can do it as a separate PR.

Could you add or augment an example showing use?

TestBufferMemoryWithChatHistoryOption is mimicking the store (that could be anything) and is an example of usage, do you think we need smth more?
