Title: added an initial ip/tcp/TcpHeader for use by clients

Mike, I don't expect you to merge this as is - but this is, in spirit, what is needed to parse Tcp Header from PCAP file. Not sure, from scodec-protocol perspective, what fields you want to hold in a TcpHeader case class (or whatever you end up calling it).
