It would be useful to include line number with FieldSizeLimitError #681
Description
When an FieldSizeLimitError exception is raised, there is no context information provided at which line number the csv-error occurred. Since the error is raised in an iterator-method, and most library-users would use the from_csv-method, the from_csv-method could add this information somehow.
Especially with big CSV files (mine is 354658 lines) this would be very helpful.
