Add support for iOS watch/today extensions

[sgleadow]

This is a great little tool, which I use regularly for debugging code signing and provisioning issues.

I've noticed that it support .app and .ipa files, but doesn't work for iOS today and watch extensions which have .appex.

I assume this can be added to the Provisioning-Info.plist like how the .app handling is defined, but I'm not sure how to find out the bundle type to add to the LSItemContentTypes.

Ah, so it has, didn't see that. I didn't notice it because I installed from brew cask and there haven't been any releases since the change was made.

If there isn't any plan for new releases to brew, I'll just install from source.
