Feature Request: Direct Read/Write Support for Polars DataFrames

[ninjaalbie]

Hi there,

I’d like to request a feature that allows direct reading and writing of data files into a Polars DataFrame, in addition to the current support for pandas. While I’m aware that converting between pandas and Polars is a viable workaround, it can be costly—particularly with large files—due to the overhead of switching formats. I think native Polars support would let us fully leverage Polars’ performance advantages without incurring extra conversion steps.

Thank you for considering this request, and I look forward to any feedback or discussion on potentially adding Polars integration!
