Enable custom configuration for iOS maps

This allows setting up the library to work with Google Maps on iOS via
`react-native link` instead of only via CocoaPods.

Because Google-Maps-iOS-Utils is not distributed as a binary (at this
time), it disables functionality that depends on this library and raises
an exception that points to the reason why there's a problem.

Additionally:

- A missing file has been added back into the AirMaps.xcodeproj project.

 The steps are as described in https://facebook.github.io/react-native/docs/running-on-device.html , however instead of opening the .xcodeproj file you should open .xcworkspace file.

 If google logo/markers/polylines etc are displayed, this is likely an API key issue. Verify your API keys and their restrictions. Ensure the native `provideAPIKey` call is the first line of `didFinishLaunchingWithOptions`.
 
-If you have ran 'react-native link` by mistake:
-
-1. delete node_modules
-2. delete ios/Pods
-3. delete ios/Podfile.lock
-4. open Xcode and delete `AIRMaps.xcodeproj` from Libraries if it exists
-5. in Build Phases -> Link Binary With Libraries delete `libAIRMaps.a` if it exists
-6. delete ios/build folder
-7. start again with the installation steps
-
 If you use Xcode with version less than 9 you may get `use of undeclared identifier 'MKMapTypeMutedStandard'` or `Entry, ":CFBundleIdentifier", Does Not Exist` errors. In this case you have to update your Xcode.
