Bugfix: require package.json in methods

Require package.json in the methods that need it, rather than when amphora-fs loads. This allows consumers to run in places that don't necessarily have a package.json file in the current working directory.

Bugfix: Exporting All Functions

Not all functions were exported from index.js file

file-stability
