Summary: RN animations currently ignore the `Slow Animations` option on the iOS simulator because we don't use UIKit animations directly. This uses a private api to get the slow coefficient and use it in the native animated driver. We only compile the private api code on simulator so this won't cause issues for app store approval. One possible issue is that the api changes in new iOS versions but I think it's reasonable to do this. Note that this won't work with JS driven animations, we could expose the slow coefficient as a constant and use that in JS but I decided not to implement it.
