fix: prevent file not found error when index not prerendered (#39)

* Fixing an issue with missing folder

If there are no prerendered pages, the build would throw a file not found error since staticDir is rimraf'ed on line 70. It's an odd corner case but I did end up hitting it.

* refactor: write additional files after SvelteKit
