feat: Add support for LiDAR, TrueDepth, External (USB) and Continuity Camera Devices (iOS 17) (#1824)
* feat: Add support for LiDAR, TrueDepth, External (USB) and Continuity Camera Devices (iOS 17)

* Rename `devices` -> `physicalDevices`

* fix: Comment out iOS 17 cameras for now

* fix: Move `supportsDepthCapture` to `format`

* fix: Fall back to `wide-angle-camera` for any unknown types

* Update CameraPage.tsx

* `descriptor` -> `physicalDeviceDescriptor`

* Update CameraDevice.ts

* Format

* feat: Expose `userPreferredCameraDevice`

Uses the new iOS 17 API where the user can prefer a default device, otherwise fall back to the first device of the available ones

* fix: Expose as property

* Add TODO comments

* fix: Format code

* fix: Compile below Swift 5.9
