Checks if an item was found in list of items and return 1 if yes, 0 if not found.
If not found, it can add that missing item to list if caller sets AddItemIfNotFound to 1.
Uses ANString style, where ANStrList is list of strings with defined separator which will be returned as well updated with new item.
Edit 2024-05-31: Adding fix to issue of false positive match when we have only 1 item.
