For an unknown reason the original Diawi plugin for Fastlane has been
removed from GitHub and RubyGems pages and can no longer be used.
This replaces it with a Node.js script which does the same job.
I tried using `diawi` and `diawi-nodejs-uploader` but both had issues,
one of them being depending on far too many useless packages.
