Support Advanced Data Protection

[BionicBison05]

iCloud stores some data without the protection of user-specific CloudKit service keys, even when Advanced Data Protection is turned on. CloudKit Record fields must be explicitly declared as “encrypted” in the container’s schema to be protected, and reading and writing encrypted fields requires the use of dedicated APIs.¹

It would be nice for Zavala to support Advanced Data Protection for some additional piece-of-mind regarding data privacy and ownership when using iCloud sync. I'm not familiar with the amount of effort required to implement this, but given that this is an outliner app Apple themselves could have made (in the best possible sense), it would make sense for it to support the same level of security as other built-in apps like Notes and Reminders.
