So since 2021/11/18, all Chinese iCloud accounts were moved from icloud.com to icloud.com.cn, which makes this whole amazing package(and some others, see icloud-photos-downloader/icloud_photos_downloader#392) not working.
To be specific,
PyiCloudSession.datais simply{'domainToUse': 'iCloud.com.cn'}now for all Chinese users.This PR introduce a fix, while not ideal because it uses an env var to toggle the switch, but is a non-breaking fix.
