[framework] future-proof: allow any kind of data in conversation

[davidschlangen]

LMMs integrate images into the conversation. We should generalise this, and let future models / agents pass other objects (like text files, sound, video, camera feeds) into the conversation.

I guess this is related to #39

I guess this entails expanding the Player ABC to handle any kind of data in addition to the messages list, and - depending on what the data is used for - the GameMaster ABCs as well.
I think a clear delineation between game-side (non-clem Player/GameMaster use) and model-side data would be good as well, as the latter needs backend support for handling the extra data. If there's no clear guidance/examples from the framework for these, I suspect that game creation using arbitrary data could get more messy than it already is...
