Issue #, if available: N/A

Description of changes: After a callout from Tyler and some additional testing, found that having the challenge option as part of the remembered state for the Composable will break since when the view is rendered, the session ID is considered started and thus can't be reused which is what happens when the Composable gets torn down and restarted. Instead, will have to add a callout to the docs change that developers will need to create a new session ID if they wish to change the camera orientation "on the fly"

How did you test these changes? Tested by attemping to "swap" camera options at runtime at the start view as well as while the liveness check is happening. Before this fix, the Composable would restart and Rekognition would return an exception saying the session is no longer valid. After this fix, attempting to "swap" the option doesn't do anything.
