Nu plugin to parse pcap file

1. Download the latest binary for your platform and extract it to a path in your $PATH. Alternatively, you can build the plugin from source by cloning this repository and running cargo install --locked --path . from the root of the repository.
2. Register the plugin with plugin add <path-to-plugin>.
3. Use the plugin with plugin use format_pcap.

The plugin exposes a single command, from pcap, which takes a single argument: a binary stream of pcap data. Meaning you can either use the open <file.pcap> directly, or pipe from a dump command like sudo tcpdump -i en0 -w - | from pcap.
