Use futures_codec for pcap async part

[Alexei-Kornienko]

There is quite handy set of traits that can be used with any async stream of data - futures_codec and tokio_util::codec that basically does the same. It would be very handy to use them to work with data received from pcap device. However to do that we need to have some kind of interface that would implement Sink and Stream.

Is there any chance that such traits can be implemented in this repository?
