The only differences between this module and Mail::DKIM::Signature are the header name, and that
'instance' is an integer rather than a base64 encoded value.

my $i = $signature->instance;
Instances must be integers less than 1024 according to the spec.
NOTE: the i= field is "Identity" in DKIM and is a base64 value, but in ARC it is "Instance" and an
integer. The parsing routine does not check that the i= value is a number.
