src/api/Animated/AnimatedImplementation.js doesn't export delay

[tomisavolainen]

const AnimatedImplementation = {
  Value: AnimatedValue,
  ValueXY: AnimatedValueXY,
  decay,
  timing,
  spring,
  subtract,
  add,
  multiply,
  sequence,
  parallel,
  stagger,
  event,

  ...testingMethods,
  __PropsOnlyForTests: AnimatedProps,
  __Animated: Animated,
  __Animation: Animation,
  __AnimatedWithChildren: AnimatedWithChildren,
  __AnimatedStyle: AnimatedStyle,
};

There should be delay function also
