Feat(dspy): from_pandas support

[Anindyadeep]

This PR adds support for to load dspy dataset from dataframes directly. Something which I personally found useful when fetching from some sources did some cleanup and get dspy dataset without saving it as a csv.

Fixes issue: #1177

PS: Just for the ruff checks, I did additional changes on types. Let me know if I need to remove that.

very nice update !

I see one else block removed in from_huggingface method is it a breaking change? It might be for few datasets, did you check?

Okay, so I reverted to the implementation along with I added the from_pandas implementation. However I am not sure how to remove the lint problem, because I face these error even when I am on the container (built from the repo).

Let me know, I will be doing that in other of my PRs too.

No fixes available (692 hidden fixes can be enabled with the `--unsafe-fixes` option).

To solve now, I kinda applied a small hack (reverting back to the contents in the main branch and adding the from_pandas function) However, I am guessing I might need to set the environment once again to not see logs like above when doing ruff fix?

Yea try syncing the repo with the current version and lemme know if you still see the errors
