Bug: switching PiP camera mode between front / back doesn't swap render output

[Liampronan]

Expected: changing this PiP config from a front/back camera layout -> back/front camera layout should swap render output.

• This is happening because this library was setup to only handle one-time configuration and dynamic config changes are a bit undefined here. I think it is a matter of tearing down/restarting the existing session properly or something to that effect.
