[Carousel] support automatic/default slider width/height

Is this a bug report, a feature request, or a question?

Feature Request: Automatic/Default Slider Width/Height

It would be incredibly helpful to have built-in support for automatically calculating the sliderWidth (horizontal carousel) or sliderHeight (vertical carousel). The implementation could support percentage values of those properties as well.

<Carousel data={data} renderItem={renderItem} {/* sliderWidth defaults to '100%' */} />

<Carousel data={data} renderItem={renderItem} sliderWidth={'100%'} />

It's possible an implementation might utilize the View component's prop onLayout:

<View onLayout={this.onLayout} {...props} />

onLayout(event) {
  const { width, height } = event.nativeEvent.layout;
  this.setState({ layout: { width, height } });
}

The width and height can then be used to calculate the sliderWidth, replacing the value used in

_getContainerInnerMargin
_getViewportOffet
_renderItem (used in parallaxProps)
_getComponentOverridableProps (calculating visibleItems)
_getComponentStaticProps (width/height for containerStyle)
