Parse table columns

[aszenz]

I have a use case where i need to parse the required tables + their columns for a duckdb sql query.

This will help in loading the table with the relevant cols needed for running the query.

I think this is already possible via duckdb c api, but not sure

Hi @aszenz! I don't have time to implement feature requests, but feel free to open a pr with your changes. At the least, it might be helpful to be more explicit with how you'd want to interact with this in case someone else wants to try and implement. For example, does each column get returned as a separate row, does it get added to a list of values, etc..

@aszenz I was thinking the same thing! I'm happy to take a stab at it too.

See: #4 @aszenz and @zacMode, I'd appreciate your thoughts on the changes.
