option to ignore non-standard columns

[matthiasfeist]

Hi!

I am currently trying to import a GTFS file for Sweden from here: https://www.trafiklab.se/api/gtfs-datasets/gtfs-sweden/
However, I am running into the following error:

Error: Binder Error: Table "trips" does not have a column with name "samtrafiken_internal_trip_number"

Unfortunately, the Swedish trips file contains a column that should not be there and it's tripping gtfs-via-duckdb up to throw an error.
It would be nice to have a option (or even make it the default) to ignore non-standard columns.

Thanks for all your work!
