External OCR engines

Previously, when ReadSoft Invoices used OmniPage to process PDF invoices, and the PDFInput INI flag was set to the default value, 1.

If the flag was not enabled, OmniPage was used directly for page extraction and interpretation.

Starting with ReadSoft Invoices 6.0.3, the PDFInput flag is no longer used. As a result, it will now use OmniPage directly if it is selected as the OCR engine under Profile settings. That is, moving forward, both OCR engines will work entirely independently from each other. Only the specified engine will be used for the entire extraction and interpretation process.
