max_tokens is not an accepted parameter

[s44002]

Out of the Documentation, there is no reference of max_tokens. the ModelSettings does not accept the max_tokens parameter..

This becomes a problem especially when using anthropic models as they dont assume a max tokens value and need one to get passed.

I am fixing the issue

Apologies, I didn't see this issue/PR in time and implemented it myself via #105

No worries, getting that fixed was the whole point.
