Implement specific property parameters

[denisinvader]

To be able to specify custom easing, round, duration etc for the specific key/item of animating object/array.

It should affect arrays and objects animations.

Animejs docs

Maybe, a helper function to get values should be implemented.

Example

Input values:

{
  x: 10,
  y: 20,
  z: {
    value: 30,
    delay: 200,
  },
}

The target value (slot scope) should be { x: 10, y: 20, z: 30 } and z key should be animated with 200 ms delay.
