Add support for printing out detected JS libraries

[lirantal]

Is your feature request related to a problem? Please describe.
While not particularly showing vulnerabilities but lighthouse also exposes an audit called 'js-libraries' which details the detected (if any) JS libraries. We could print them out as extra meta data tool

Describe the solution you'd like
This will probably require a bit more goofing around work with the data from lighthouse so be prepared for that. Ideally we'd also need to add a flag such as --js-libs or something to add this metadata.
