 Returns the the duplicate of the underlying Buffer that backs this InputSource. The content of the returned buffer will be that of the underlying buffer. Changes to
returned buffer's content will be visible in the underlying buffer, and vice versa; the two buffers' position, limit,
and mark values will be independent.
