Feature Request: Autoplay, Loop

Hi, I'd love to use this nice slim library in my recent project but I have to switch to something else mostly because it lacks RTL support (in RTL the swipe gesture moves slides to the opposite direction); I guess it should be an easy fix, probably checking `I18nManager.isRTL` and changing some `-/+` would do the trick.
My other suggestions, if they fit in the scope of this project, would be adding the ability to loop through data by adding some paddings to the data and having `autoplay` option, just like a slide show.

The issue names no files or tests. Start by reviewing the carousel's swipe direction and slide data handling, using I18nManager.isRTL as the stated RTL entry point; first agree whether RTL support, looping, and autoplay are in scope, then define tests and completion criteria.
