Formatted output of the verification

One important feature of a verifier is the ability to document results. To allow this, the reader
provides verification reports that can be accessed over the various interfaces.
If a verification report has been configured, this is generated and output each time a read
was successful.
A verification report consists of two parts:
● The verification settings,
● The verification result.
Verification settings
With %v (lower-case "v"), you obtain an output of the all the settings relevant for verification
in the printed order.
All field values are separated by semicolons. The field names are not part of the report.
