* Fix TSIG bug releated to ID substitution TSIG accounts for ID substitution. This means if the ID in the DNS message is changed by for example a forwarder, TSIG calculation should use the original message ID (from the TSIG RR). I have a test for this as well, but it seems tsig_test.go has been removed, so not sure where to put it now. * Add tests for TSIG bugfix
