`UploadFile` has the following `async` methods. They all call the corresponding file methods underneath (using the internal `SpooledTemporaryFile`).

* `write(data)`: Writes `data` (`str` or `bytes`) to the file.
* `read(size)`: Reads `size` (`int`) bytes/characters of the file.
* `seek(offset)`: Goes to the byte position `offset` (`int`) in the file.
    * E.g., `await myfile.seek(0)` would go to the start of the file.

	// write a zip file
	archive := new(bytes.Buffer)
	w := NewWriter(archive)

	for i := range files {
		f := &files[i]
		f.crc32 = crc32.ChecksumIEEE(f.content)
		size := uint64(len(f.content))
		f.uncompressedSize = size
		f.compressedSize = size

		var compressedContent []byte
		if f.method == Deflate {
			var buf bytes.Buffer
			w, err := flate.NewWriter(&buf, flate.BestSpeed)
			if err != nil {
