add a function to change the sorting of files in the list of merged files.

Sometimes there is a need to merge multiple consecutive videos using ME

For example.
20230620-110102.mp4
20230620-110402.mp4
20230620-110702.mp4
is the file name of a time-sorted video series.

If you drag and drop into ME Merge directly from the Win10 File Explorer, the sorting will become
20230620-110702.mp4
20230620-110102.mp4
20230620-110402.mp4
At the end of the day, the sorting goes to the top.

However, this does not happen if you drag and drop from ME's own file manager.
I would like to add a function to change the sorting of files in the list of merged files.

(auto order by file name,file time,ect.)
