Scroll isn't locked on y-axis (on mobile)

[maximelebreton]

Hello @freddie-nelson, and thanks for your work on this slider!

When you're on mobile, and on a page that can scroll, if you start to slide, the page scrolls with the slide, and I think thats a unexcepted behaviour.

I try to pass the preventDefault() event, but it doesn't seem to be transmitted.

The ideal would be to have an option to prevent scroll on x-axis, y-axis and both,
like:
preventScroll: true, x, y

Thanks!
