GoogleMapsInitializer

A singleton object to manage the initialization of the Google Maps SDK.

This object provides a state machine to track the initialization process and ensures that the initialization is performed only once. It also provides a mechanism to reset the initialization state, which can be useful in test environments.

The initialization process consists of two main steps:

1. Calling MapsInitializer.initialize(context) to initialize the Google Maps SDK.

2. Calling MapsApiSettings.addInternalUsageAttributionId(context, attributionId) to add the library's attribution ID to the Maps API settings.

The state of the initialization is exposed via the state property, which is a State object that can be observed for changes.
