OCR Progress and Performance Tracking

The IronTesseract object has an OcrProgress event that can be used to track OCR progress. We can track progress using the OcrProgressEventArgs object sent to this event after any page of OCR text has finished reading.

This is useful in GUI applications, Web Applications, and CLI alike to keep users informed of how long they may need to wait.
