Svelte integration

- [x] I have looked through the [documentation](https://fiduswriter.github.io/simple-datatables/documentation/) to try to see if this feature already exists.
- [x] I have looked at the [demos](https://fiduswriter.github.io/simple-datatables/demos/) to see if one of them does what I want, but none of them did.

It will be great if you can add a doc about how to integrate simple-datatables to Svelte
