LifecycleScopeFactory
Factory holder for DispatchLifecycleScope's.
By default, create returns a MainImmediateContext.
This factory can be overridden for testing or to include a custom CoroutineContext in production code. This may be done in Application.onCreate, or else as early as possible in the Application's existence.
A custom factory will persist for the application's full lifecycle unless overwritten or reset.
reset may be used to reset the factory to default at any time.
