`UploadFile` має такі асинхронні `async` методи. Вони всі викликають відповідні методи файлу під капотом (використовуючи внутрішній `SpooledTemporaryFile`).

* `write(data)`: Записує `data` (`str` або `bytes`) у файл.
* `read(size)`: Читає `size` (`int`) байтів/символів з файлу.
* `seek(offset)`: Переходить до байтової позиції `offset` (`int`) у файлі.
    * Наприклад, `await myfile.seek(0)` перейде на початок файлу.
