iCloud Drive support

Feature Request

A feature you'd like to see

I believe iCloud Drive support would be nice to have. This could be done by either authenticating with iCloud or using a share-link from iCloud Drive that requires no authentication.

Additional remarks

this could either be done by pasting a share link that requires no authentication and acts as a direct link to the database file or authenticate with iCloud and store the authentication token so that the file can be fetched each time Tusk needs to

How would authentication work? Oauth isn't supported.

This project authenticates with iCloud somehow https://github.com/ndbroadbent/icloud_photos_downloader

If two-factor authentication is too much to handle then users can use an app specific password.

More specifically, that project is using ndbroadbent/pyicloud for icloud authentication
