Obtains the headers for the part currently being processed.
Note that the [struct@MessageHeaders] that are returned are owned by the MultipartInputStream and will be replaced when a call is made to [[email protected]_part] or its async counterpart, so if keeping the headers is required, a copy must be made.
Note that if a part had no headers at all an empty [struct@MessageHeaders] will be returned.
