Simplified Deeplink Testing

deeplink.py

Script to make it easier to test deeplinks from the command line without remembering arcane
incantations to conjure the spirits of the computer.
Add to your path somewhere, and run in your project directory passing the url of the deeplink.
If the platform name 'ios' or 'android' is in the working directory name, it doesn't need to be
passed as an argument, though this can be done as well. The Android package name can also be
explicitly included.
