For SmartZone OCR

Each SmartZone OCR instance can be used from multiple threads.

For faster processing Accusoft recommends using SmartZone OCR instances attached to the specific threads to avoid extra locking and reusing existing instances as long as possible without disposing to save the time on re-initializing the recognition backend.
