Error on extraneous columns

[ion-elgreco]

Not sure if this exists, but when I do validate, it doesn't throw an error on extraneous columns. This was a feature in patito for example

[borchero]

This is intended. Other than this is the behavior in patito: would you have expected dataframely to keep the columns as well? If so, what would be your use case?

[ion-elgreco]

So using the return value of validate removes the columns, but we were only using it to see if there were errors, so we just wanted to receive an error if there are extra columns
