PI UFL ._OK file rename should be after parsing to avoid data loss during shutdowns

My understanding of UFL (confirmed by tech support) is that it will rename files to ._OK extension before loading lines into memory. This means that if the service is stopped (such as during an update) and it has not completely read into memory and parsed the file, the data will be lost, and the file must be manually renamed so that it can be processed again.
The beauty of UFL is the ease of running large backfilling operations for history recovery from third party systems. If the file can instead be renamed after it is parsed (rather than before), this will eliminate the loss of data concern.
