Crashes when there is an Authority section #54

Open bortzmeyer opened 2 years ago

bortzmeyer commented 2 years ago

If we try to encode a response which has an Authority (nslist) section, the library crashes

** (FunctionClauseError) no function clause matching in :inet_dns.encode_res_section/3

Answer or Additional section do not have the problem.
