TwainControllerRegisterTwainCallback Method

Sets up a callback for TWAIN device messages instead of using the traditional message loop. This should only be called when using the TwainController directly; the Device object automatically handles the callback.

The callback feature is only supported when using the TWAIN 2.0 Data Source Manager
