Added Support for React Native Projects

[prscX]

Hi @javiersantos,

First of all I would like to appreciate for creating such a cool library.

I have created a React Native bridge plugin for using this library with React Native projects

I have added the same in README. Can you please merge this request so that if someone looking to use this library for React Native projects can easily do the same.

Please let me know in case any changes are required.
