[iOS]Camera permission error occurs when entering the background

[hyunseokYang]

Describe the bug

Hello.
I'm inquiring about an error while testing this package in iOS.

in FaceLivenessDetectorView,
After reaching the DisplayState.displayingLivense state
When the app is inactive (or background)
FaceLivenessDetectionError(code: 5, message: "Camera permissions have not been granted.", recoverySuggestion: "Prompt the user to grant camera permission.") An error occurs.

My example code
...
...

FaceLivenessDetectorView(
                sessionID: sessionId,
                region: region,
                isPresented: Binding(
                    get: { true },
                    set: { _ in }
                ),
                onCompletion: { result in
                    switch result {
                    case .success:
                        // success process
                    case .failure(let error):
                        /// Here !! error occurs
                    default:
                        // default process                 
                    }
                }
            )

Of course, the camera permission was already authorized.

Hi @hyunseokYang, thanks for opening this issue.
The team will take a look and post updates here.

This has been fixed in version 1.3.1: moving the app to the background during a liveness check now results in a .userCancelled error.
Please update your dependency.

Thanks!
