service = "all" | "text" | "meta" parameter is missing in parser.from_buffer() method.

parser.from_file() have a parameter service, if we pass it as "text', it ensures that the file metadata description is not included in the output, like name of the author for MS-word doc., but from_buffer() method does not have this parameter, and we get the file metadat description appended in "content" in the output.
