Enable animation on inner nodes of the options

### Feature Proposal

Currently the animation properties can be defined only at base level of an element or its options.
When you want to animate properties which are belonging to an inner object of the element or options, is not possible.
Use case could be font or padding of elements.

### Possible Implementation

Manage the properties to configure the `animations` which are representing the path where the properties are located.

```javascript
animations: {
numbers: {
properties: ['font.size'],
type: 'number'
},
},
```

With above config, the animation will be applied to the inner object `font` and its property `size`.
