Feat: add inferFromPackageJson option for filling option smartly

[imcuttle]

Add inferFromPackageJson option (Default: true).
We don't need to set name / license / private / homepage / desc definitely.
There are inferred from closest package.json.

@imcuttle Thanks for the PR; however, I am not inclined to merge this one, unfortunately, as inferring from the nearest package.json is too Node.js specific. A higher order utility could easily wrap this package and add support for option inference. But I don't think this utility should be that higher order utility.
