This function will clean up and free memory allocated during the WIA session.
Whenever calling any of the LEADTOOLS WIA functions except for L_WiaAcquireSimple. The L_WiaInitSession function must be called to begin a session prior to calling the other function. For each call to L_WiaInitSession there must be a call to L_WiaEndSession to end the session. The L_WiaEndSession function should be the last function to be called in the toolkit.
Note: You do not need to call L_WiaEndSession if you are using the high-level L_WiaAcquireSimple function, since it handles session initialization, session end, and device selection automatically.
