A method that takes a `raw` buffer and `metadata` as parameters and
     * returns a promise that resolves to an array of `Document` instances. It
     * uses the `parseOfficeAsync` function from the `officeparser` module to extract
     * the raw text content from the buffer. If the extracted powerpoint content is
     * empty, it returns an empty array. Otherwise, it creates a new
     * `Document` instance with the extracted powerpoint content and the provided
     * metadata, and returns it as an array.
