+The first argument of `scan` is the type of item to scan, and the second argument is the entrypoint. It returns an array of `FileChunk` when `type` is `'files'`, `DirChunk` when `type` is `'directories'`, and both when `type` is `'all'`. The `entry` argument can be anything as long as it exists in the filesystem, though it would return an empty array if it's not a directory.
