+  **Optional** Post-fills the `scans.csv` file with more realisitic (but still fake) values for the following columns: `db_create_start`,`db_create_stop`,`scan_start_date`,`scan_stop_date`. These values are not in the input sarif and it may be beneficial to have date values near the present. Otherwise `sarif-extract-scans-runner` will have populated these columns with the value `1970-01-01`.
