* \brief Given a NAPTR record, generate a binary form, as would appear in DNS RDATA
*
* This is part of a DNS answer, specific to NAPTR. It consists of all parts of
* the NAPTR record, encoded as it should be in a DNS record.
*
* There is no buffer size passed to this function since we provide
* the data ourselves and have sized the buffer to be way larger
* than necessary for the tests.
*
* \param string The NAPTR record to encode
* \param buf The buffer to write the record into
* \return The number of bytes written to the buffer
