`UploadFile` 에는 다음의 `async` 메소드들이 있습니다. 이들은 내부적인 `SpooledTemporaryFile` 을 사용하여 해당하는 파일 메소드를 호출합니다.

* `write(data)`: `data`(`str` 또는 `bytes`)를 파일에 작성합니다.
* `read(size)`: 파일의 바이트 및 글자의 `size`(`int`)를 읽습니다.
* `seek(offset)`: 파일 내 `offset`(`int`) 위치의 바이트로 이동합니다.
    * 예) `await myfile.seek(0)` 를 사용하면 파일의 시작부분으로 이동합니다.
