Add temperature and top-p

[RyanMarten]

Doing this since Negin requires it for UnnaturalInstructions.

Also to get an idea of the best way to do #62 and #74.

This is just a stop gap before I get to those two issues.

Are these the right defaults to use?
Should it not be None?
https://docs.litellm.ai/docs/completion/input:

    temperature: Optional[float] = None,

If it is None, I assume litellm doesn't pass the temperature and the provider will the default that they have configured.

Fixing this!

Test with

from bespokelabs.curator import Prompter
from datasets import Dataset

dataset = Dataset.from_dict({"prompt": ["write me a poem"] * 10})

prompter = Prompter(
    prompt_func=lambda row: row["prompt"],
    model_name="gpt-4o-mini",
    response_format=None,
    temperature=TEMP,
)

dataset = prompter(dataset)
print(dataset.to_pandas())
