`UploadFile` には次の `async` メソッドがあります。いずれも内部で対応するファイルメソッド（内部の `SpooledTemporaryFile`）を呼び出します。

- `write(data)`: `data`（`str` または `bytes`）を書き込みます。
- `read(size)`: `size`（`int`）バイト/文字を読み込みます。
- `seek(offset)`: ファイル内のバイト位置 `offset`（`int`）に移動します。
    - 例: `await myfile.seek(0)` はファイルの先頭に移動します。
    - 一度 `await myfile.read()` を実行して、もう一度内容を読みたい場合に特に便利です。
- `close()`: ファイルを閉じます。
