Additional output fields from `package.json`

[nima-ap]

Would it be possible to allow the consumer to define additional fields that they would like extracted from package.json and added into the output JSON? For instance, I'm looking to get the homepage field. I think with a simple addition to the options and reflection in the LicenseMetaAggregator this can be accomplished.

I can also help with the implementation and PR if you'd prefer.

@nima-ap Sounds like a helpful functionality. I’d be happy if you could provide a PR! 😄
