Sometimes not all signatures from a bundled signature files are relevant.
For example jdk-unsafe contains also String.format(...) methods. However in most of the cases the Locale is not relevant (i.e. when only using String format specifier %s).
It would be nice to allow to either completely skip checking individual signatures or at least lower the severity of the log message (from error to warn).

I know about @de.thetaphi.forbiddenapis.SuppressForbidden but this would need to be used everywhere in the code where the affected signature is being used.

This is related to #219 but requires a more granular parametrisation.
