Parameter `--collect dirs-1st-last-file` counter isn't treating 9 as less than 10, 11, etc.

Describe the bug
The --collect dirs-1st-last-file isn't properly counting sequences that don't have padding.

Debug enabled? Note run circumstances. Attach ConsoleLog (see wiki).
No.

Repro steps:
Steps to reproduce the behavior:

1. listall.py -d "." -i 1 -fmt summary -xd ".sync" -c dirs-1st-last-file --output file --filename "f3-archive.txt"

Expected output? What do you see instead?
In the F3 archive folders like 1947.06 - 9668704 - Bakersfield, California output as:

  Page 1.jpg
  Page 9.jpg

When it should show as:

  Page 1.jpg
  Page 13.jpg

Screenshot or video (opt.)?
NA

Version (see listall.py --version)? OS? Python version?

1. listall.py: 0.0.2.1
2. OS: Windows 10 Professional 64bit
3. Python: 3.12.1

Additional context
It might make sense to simply snag the code from pattern break

Actually this may be as simple as just doing a --sort isequence, but maybe I should make that the default for -c dirs-1st-last-file?
