Add `useNativeDriver` as a configuration option

[felixclack]

Using this library the latest version of React Native (0.63.4) raises warnings about explicitly setting useNativeDriver for the Animated functions.

I considered hardcoding the value as false for instances of Animated.event and Animated.spring to maintain the existing behaviour but felt like exposing it as an option adds very little extra complexity to the library while ensuring people can opt in to the native animations if they want.
