Is your feature request related to a problem? Please describe.

Some fields may have a 12 digit number but it's an internal system identifier which doesn't benefit from redaction.
It would be nice if these attributes could be passed through without having the value treated as a credit card number.

Describe the solution you'd like

Add an ignorelist to the redaction processor so it can be explicitly set to pass suspicious data.

Describe alternatives you've considered

Other processors don't seem to have the regex matching and replacement ability that the redaction processor has.

Additional context

The "allowList" in the processor seems to provide this capabillity at first glance but it is actually different. Adding the ignoreList will give users a way to proceed without having the modify their system identifiers or other drastic measures.
