Fill CSV text if there are non-even rows

Should you try to run `csvdiff` against 2 csv files with either file having a
non-even columns, there will be an error. As such, the csv files need to be
"filled" before running `csvdiff`.

* gn3/csvcmp (csv_diff): For non-even rows in the csv files, fill the csv
rows.
