Add support for sorting with the file metadata change time (ctime)

Add a sorting option for sorting files based on when file metadata last changed / inode change in linux. e.g. when a file was last moved or renamed on disk instead of when file contents changed
This corresponds to the -c option in GNU ls

No files or tests are named. Start by locating the CLI's existing file-sorting options and metadata handling, then compare the behavior with GNU ls -c on Linux. Done means users can select sorting by inode metadata change time, such as after a file is moved or renamed, with coverage for the new option.
