Allows you to specify the tag name used for the splide__list (ul) and splide__slide li with react component

[lezan]

In NextJS I am getting Did not expect server HTML to contain a <div> in <li>. because of what I am rendering as child of SplideSlide.

Could be possibile to allow to specify the tag name for splide_list (https://github.com/Splidejs/react-splide/blob/master/src/js/components/SplideTrack/SplideTrack.tsx#L13) and splide__slide (https://github.com/Splidejs/react-splide/blob/master/src/js/components/SplideSlide/SplideSlide.tsx#L12) like with Splide root component (https://splidejs.com/integration/react-splide/#tag, https://github.com/Splidejs/react-splide/blob/master/src/js/components/Splide/Splide.tsx#L163).

Thanks
