Continuing the theme of downloading segmented files
The original segment downloader got updated to take a formatting code in the filename. It replaces the formatting code with the number.
But once the segments are downloaded, you have to cat them into a single file. The problem is numbered files get sorted with 1000 before 10. This is a job for another program which takes another formatting code in the filename. It cats all the files in a numerical range, replacing the formatting code with the number.
