Allow Fscan programs to check for "nosfts" file
Description
This MR lets the Fscan programs check for the nosfts
file if the SFT catalog length is zero length. If the file exists, then the program exits gracefully. If not present, then the program exits with an error.
It is preferable to merge !2232 (merged) first since that's the primary way the nosfts
file gets created, though it could be manually created for some specific use cases.
