Should we return some of Datafusion Errors instead? Maybe IoError or InternalError?

I am not sure why the from_proto and to_proto modules have their own error types and don't use DataFusionError (or even wrap DataFusionError)
It does seem like that would be an improvement. Maybe I can file a follow on ticket to do so.
