Org-mode exporter backend for Svelte components

ox-svelte is an opinionated Org-mode exporter backend that generates a standalone Svelte component.

While ox-html technically generates a valid Svelte component, the resulting file includes a lot of junk. They are useful for standalone HTML documents, but not for components.

ox-svelte fixes this by performing minimum preprocessing and postprocessing and exposing metadata as a module-level JavaScript property.
