Carthage support

[TofPlay]

Hi, Interesting component 🙂 For iOS projets it's will be great to make your component Carthage compatible

Take a look at these articles:

• Ruthlessly Simple Dependency Management with Carthage
• Carthage Tutorial: Getting Started
• Making Carthage-compatible Frameworks with Swift
• Swift Cross Platform Framework (section Configure targets for Carthage) 👍

On your README.md add on top and add section for the installation with Carthage.
