 *  New: `MediaType.parameter()` gets a parameter like `boundary` from a media type like
    `multipart/mixed; boundary="abc"`.

        source = Buffer().writeUtf8(multipart),
      )

    val part = parts.nextPart()!!
    assertThat(part.body.readUtf8()).isEqualTo("abcd\r\n--simple boundar\r\n\r\nefgh")

 *     val part = multipartReader.nextPart() ?: break
 *     process(part.headers, part.body)

 *
 * Note that [nextPart] will skip any unprocessed data from the preceding part. If the preceding
 * part is particularly large or if the underlying source is particularly slow, the [nextPart] call
 * may be slow!
