Feature request description

It would be nice to have support for svelte projects (raw Svelte, Sapper or SvelteKit projects), similar to the React and Vue support that exists currently.

Any extra info

Currently when you run depcheck on a Svelte project, it reports imports used within .svelte files as unused. Have not tested with raw Svelte projects or SvelteKit, but assuming that it has problems interpreting the .svelte files.
