Improvement suggestion

[sommella]

Hi,

Thank you for this tool, very useful!

A couple of suggestion:

1. Using aggregate action header and date are not aligned
2. Is possible to change the protocol number with actual protocol name according: https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml
3. Using the command line tool, would be nice to read data from a file and/or a variable or directly from a pipeline (for performing analysis on exported data)

Thanks
