Represents the DNS over TCP layer. DNS over TCP is described here: https://tools.ietf.org/html/rfc7766 . It is very similar to DNS over UDP, except for one field: TCP message length which is added in the beginning of the message before the other DNS data properties. The rest of the data is similar.
Note: DNS over TCP can spread over more than one packet, but this implementation doesn't support this use-case and assumes the whole message fits in a single packet.
