Add node_modules artifact extraction ability

[G-Rath]

@another-rex could you expand a bit on the initial implementation for this? If I recall correctly when we last spoke currently we want to do this using the node_module/.package-lock.json file since the interfaces don't currently support walking directories (which also blocks #790 unless Python has a similar file?)

And should this only happen in containers?

Yep, let's use node_modules/.package-lock.json until we update the extractor interface.

And should this only happen in containers?

Yes, I think this just means we don't have an init function that runs registerExtractors()

For #790, I think .egg-info is a single file (a zip file I believe)? I'm not sure though I haven't looked into it enough. It will prevent us iterating through site-packages / dist-packages folders though.

Apparently I completely forgot to link #851 with this - that adds at least initial support for scanning some node_modules
