Add an animation for Slider value change

## Describe the Feature
A prop to enable animating the movement of the Slider since just by updating the value it looks very "grainy" and is subpar for anything presentable

## Possible Implementations
There is the same functionality in https://github.com/jeanregisser/react-native-slider and it works well for iOS, but for me disables the Slider when testing in debug mode on Android.

issue 中没有指定文件或测试。首先定位 Slider 组件并查看值更新如何移动控件，然后对比所引用的 react-native-slider 行为。当可选择启用的动画能够在 iOS 和 Android 上平滑 Slider 的值变化，且不会在 Android 调试模式下禁用 Slider 时，即视为完成。
