1) Thank you for pointing the moment with 0 temp, I think we can make `agency.TextToTextParams{Temperature *int}` where nil gonna be passed down like `0` and 0

1) Thank you for pointing the moment with 0 temp, I think we can make `agency.TextToTextParams{Temperature *int}` where nil gonna be passed down like `0` and 0 gonna be mapped to `math.SmallestNonzeroFloat32`. We also will add the ability to use seeds though 2) "I was hoping this would be a drop in replacement for langchain" - why don't use use langchaingo then? The thing is - we don't like langchain much. To is it looks too complex, we thing we can do better, simpler. The final goal is to make a library that can replace langchain and/or autogen but it's definitely not gonna be "drop-in" replacement
