Bug when there are unknown fields in forensic report

[davidwestlund]

Thank you for a great program.

If there are unknown fields in a forensic report, the program crashes. This can happen in the function "parsed_forensic_reports_to_csv" if the call to "parsed_forensic_reports_to_csv_rows" returns rows with fields that are not defined in the "fields" variable. One solution is to copy the known fields to a new structure (this begins at row 732 in init.py):

    for row in rows:
        new_row = {}
        for key in new_row.keys():
            new_row[key] = row[key]
        csv_writer.writerow(new_row)
