> Currently when a row does not have the correct number of columns an error is
> generated and parsing stops. It would be better if this behavior was
> customizable depending on the caller so that rows could either be ignored or
> altered to have the correct column count.
> Ideally there would be some builtin handlers for this but it would be good
> for the caller to be able to implement their own handler if they wanted to
> collect the malformed rows and report them to a different component or maybe
> add fields based on the existing fields in the row.
