Optional loading of the Tourguide Controller

[cip123]

Hello, thanks for writing this library. It is handy, and it helps a lot with onboarding users.

However, I am interested in one functionality.

As I said, I am using this Tour Guide to onboard the user, and after they complete it, I save that the user has taken the guide in the AsyncStorage.

So, for a given user, the Tour Guide will only be displayed once, but it will be loaded every subsequent time the user opens the application.

Since the Tour Guide causes multiple re-renders to register the steps and determine if it can start, this causes the screens to re-render a few times, although I am not using it.

Would you happen to have any suggestions on how to fix this?
