Feature request: Improve error messages

[alekkova]

Is your feature request related to a problem? Please describe.

There are only a handful of error cases defined for face liveness session without any additional description. One of those errors is also an unknown error. Such limited error reporting makes it hard to understand issues that users are facing.

An example of receiving an unknown error was also reported here: aws-amplify/amplify-swift#3546

Describe the solution you'd like

Provide better error descriptions. Avoid using an unknown error or attach the underlying error description to the error case.

Describe alternatives you've considered

There are no alternatives.

Additional context

No response

My implementation also returns unknown errors a lot of the times, I can't figure out what the problem is... This feature would be very appreciated
