Any plans for checking the files array or npmrc

I am regular user of pkg-ok and loves it 😄

I try to be explicit about the files I publish to the npm using the `files` array or the `.npmrc` file. I have been bitten quite a few times, where as per `pkg-ok` the paths are correct, however, I forgot to add them to the `files` array.

I am checking to see if you have any plans to check the published files and then validate paths. Not only it makes sure that the path exists, it also makes sure that paths are also published to npm.

I am happy to work on this feature (only if you want to add it).

Thanks
