perPage attribute does not work

It seems siema doesn't accept the perPage parameter as an string. If I change the number or introduce a parseInt on the svelte-carousel code before passing the prop to siema it works.

I found that using "{1}" instead of "1" in the props also work, so maybe just including on the documentation could suffice.
