Carthage support

[Tof]

Hi,
For iOS and macOS 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.

Hi @TofPlay,

Thank you for your contribution! 👍
I have added Carthage support to the framework and updated the README with the shield and with installation instructions 🎉
