White Rabbit: Append a timestamp to the scan report name

[megan-lien]

Is your feature request related to a problem? Please describe.
Currently, the scan report is written to a working folder with a name of ScanReport.xlsx. We have to manually re-name that file if we want to run it again, or else the results will be overwritten.

Describe the solution you'd like
It would be preferable to append a timestamp to the name of the scan report so we don't overwrite the output. Like: ScanReport_ 20221108T095900

Describe alternatives you've considered
Manually re-naming the ScanReport after it's created or moving it to another folder

Additional context
When we expect to run the report on a regular basis, this would remove a manual step and allow us to archive the results.
