Support for PCAP file format

[pkess]

Is your feature request related to a problem? Please describe.

I would like to analyze some can traffic with wireshark. With Wireshark it is possible to check e.g. CANopen communication as you see here: https://wiki.wireshark.org/CANopen.md

Describe the solution you'd like

There is the pcap file formt supported by wireshark to load can traces https://wiki.wireshark.org/Development/LibpcapFileFormat
It would be nice to use python-can to record or convert into pcap file format for further processing

It appears like wireshark includes a utility for converting regular ascii hex logs to pcap -- https://www.wireshark.org/docs/man-pages/text2pcap.html
