fix(netxlite): reject replies with wrong queryID (#732)
This diff has been extracted from c2f7ccab0e

See https://github.com/ooni/probe/issues/2096

While there, export DecodeReply to decode a raw reply without
interpreting the Rcode or parsing the results, which seems a
nice extra feature to have to more flexibly parse DNS replies
in other parts of the codebase.
