Usar `UploadFile` tiene varias ventajas sobre `bytes`:

* No tienes que usar `File()` en el valor por defecto del parámetro.
* Usa un archivo "spooled":
    * Un archivo almacenado en memoria hasta un límite de tamaño máximo, y después de superar este límite, se almacenará en el disco.
* Esto significa que funcionará bien para archivos grandes como imágenes, videos, binarios grandes, etc. sin consumir toda la memoria.
* Puedes obtener metadatos del archivo subido.

Utilizar `UploadFile` tem várias vantagens sobre `bytes`:
