Tracking tokens and spend

[kitsamho]

Not sure if this is really out of scope for a library like this - but token usage using OpenAI keys can seriously add up $$. Is there a way we can for each instantiation of an object keep a tally of tokens used as an attribute? Maybe that's a bit clunky.

We did not have any plans for such a functionality. But we will investigate the possibilities of adding this.
