Thank you for this awesome package.

I want to get files downloaded, so I tried several ways.
But I couldn't get download link.

https://api.chatwork.com/v2/rooms/{room_id}/files/{file_id}?create_download_url=1

According to API document, in order to download file, download link must be created first.
But I can't see create_download_url key in this package.

Please let me know if I miss something.

Best Regards

Xianzhe
