Package size and number of dependencies

[armano2]

Hello, i'm a little concerned about size of this package and number of dependencies that it requires to run,

this package has 66 dependencies and weights 175kb with all its dependencies, as a comparison yargs has 16 dependencies and weights 76kb,

most of code in this package actually come from reading and normalizing package.json and that should be a trivial task as this package uses optionally 2 fields description and version.

my suggestion is to replace normalize-package-data and read-pkg-up with find-up and simple if condition.

this change should allow to reduce number of dependencies by half and reduce size by 70%

I guess we could remove it, but it would be a breaking change as we expose the package as a .pkg object. We would also have to document that it's not normalized and how the user needs to manually normalize it if they want to access properties.
