Force FaceID in files app

Summary

Force unlock via FaceID in files app as standard

Motivation

When opening a Cryptomator vault in the Apple Files app, the Cryptomator interface opens and requests that the folder be unlocked.
To be able to use FaceID for unlocking I have to press the button "Unlock via FaceID" so that the iPhone unlocks the vault via FaceID.
If FaceID is enabled for this Cryptomator vault, it would be much faster and more convenient if FaceID is tried directly by default when opening the files, without having to select it first.

Thank you for your feature request! Just wanted to let you know that we actually considered this right from the beginning but encountered an upstream bug that was also mentioned in #72. We just got a notification from Apple that this upstream bug is probably fixed in iOS 16 but we haven't confirmed it yet (Edit: it is indeed fixed).

Regardless of the upstream bug, we could implement a "workaround" like this:

1. Unlock vault instantly via Face ID / Touch ID.
2. If it fails, step 1 will be skipped and the unlock screen will be shown.

It would be nice, if you implement this workaround :) Are there an plans to do this?
