Add hasPrevPage and hasNextPage booleans

[jasongerbes]

This PR adds hasPrevPage and hasNextPage booleans to SnapCarouselResult to indicate if there's a previous or next page to scroll to.

@richardscarrott, I have updated the README.md and Storybook components to use these new properties. You may also want to update the CodeSandbox example after this change has been released.

Closes #28.

LGTM -- thanks for sending this PR, appreciate it 👍

I'll publish a new release once I get a sec.

[richardscarrott]

This is available in a pre-release https://github.com/richardscarrott/react-snap-carousel/releases/tag/v0.5.0-next.1 -- npm add react-snap-carousel@0.5.0-next.1

I'll run it in production for a little bit and then make it available as v0.5.0 proper.

Now published as 0.5.0 https://github.com/richardscarrott/react-snap-carousel/releases/tag/v0.5.0

Thanks @richardscarrott! 🎉

Unrelated, have you considered adding support for autoplay?

It’d be neat if react-snap-carousel could be used to create something similar to Apple’s scroll-based carousels with autoplay:

@jasongerbes I think that UI could be built relatively easily on top of what react-snap-carousel already offers -- imo it's prob best react-snap-carousel doesn't get involved with the timer logic as, for example in that instance, each item's video could be a different length so an out-the-box autoplay function likely wouldn't suffice -- there is a very basic example of autoplay here -- #17

re: playing the video when an item becomes active, that could be done using activePageIndex (similar to showing the text here) or alternatively I've found
useInView from framer-motion to be quite effective as it factors in all scroll parents.
