rfc3161-client has insufficient verification for timestamp response signatures

Impact rfc3161-client 1.0.2 and earlier contain a flaw in their timestamp response signature verification logic. In particular, it performs chain verification against the TSR's embedded certificates up to the trusted roots, but fails to verify the TSR's own signature against the timestamping leaf...
