New fork of this project's repository being actively maintained (django-islands)

My name is davi silva rafacho and I am a python developer at a company in Brazil. We loved this library built by citusdata, but a few years ago it stopped receiving updates and I decided to create a fork of it to continue developing, improving and correcting it. If you are having any problems or suggestions for improvements, please create an issue at [django-island](https://github.com/yellow-devs/django-islands.git)

I updated the link with the new organization name
