How to use the azure-storage-file.azure.storage.file._download_chunking._download_file_chunks function in azure-storage-file

stream.write(file.content)
            file.content = None

        # If the file is small, the download is complete at this point.
        # If file size is large, download the rest of the blob in chunks.
        if file.properties.content_length != download_size:
            # At this point we would like to lock on something like the etag so that
            # if the file is modified, we do not get a corrupted download. However,
            # this feature is not yet available on the file service.

            end_file = file_size
            if end_range is not None:
                # Use the end_range unless it is over the end of the file
                end_file = min(file_size, end_range + 1)
