 `--input-file` extends the functionality of *csv2cve* for other formats like JSON.  It also allows cve-bin-tool to specify triage data so you can group issues which may have been mitigated (through patches, configuration, or other methods not detectable by our version scanning method) or mark false positives.  Triage data can be re-used and applied to multiple scans.  You can provide either CSV or JSON file as input_file with vendor, product and version fields. You can also add optional fields like remarks, comments, cve_number, severity.
