Create a config plugin for the sdk

Test

1. Run npm install in the root folder
2. cd into *example`
3. Run npm install
4. run npx expo prebuild --clean
5. run npx expo run:ios or npx expo run:android
6. Once the build is complete and the app is running on your simulator, make sure that the terminal logs withIterable plugin, followed by a long configuration file. That means the config is correct.
