Description
This would greatly improve encryption/packing speeds on devices without onboard AES acceleration, such as the Raspberry Pi. I find my Pi 4 performs extraordinarily well in all regards within Nextcloud except for the Backup app as it falls back to aes-256-cbc. The performance of Adiantum (especially ChaCha12) on the Pi 4 is more than enough to keep up with USB 3.0 drive, where I have Raspberry Pi OS installed, meaning encryption speeds would no longer be a bottleneck.
Edit: Adiantum has been a part of the kernel since 5.0, and 5.10 on the Raspberry Pi. Most modern devices likely have this cipher as an option.

Research direction
No files, tests, or entry points are named. Start by locating the existing aes-256-cbc encryption path and its tests, then determine how cipher selection is represented; done means Adiantum is supported for devices without AES acceleration and its behavior is covered by tests.
