RTL support

[pkocak]

Carousel doesn't support RTL. When i change my page dir RTL my images in ul with className=".BrainhubCarousel .BrainhubCarouseltrackContainer .BrainhubCarouseltrack.BrainhubCarousel__track--transition" changes correctly however, this ul's translateX always gives minus number pixels.

Solution can be changing translateX to positive number pixels of ul with className=".BrainhubCarousel .BrainhubCarouseltrackContainer .BrainhubCarouseltrack.BrainhubCarousel__track--transition" when page dir="rtl

For RTL use please add the RTL plugin to your carousel as described here https://brainhubeu.github.io/react-carousel/docs/examples/rtl
