Enhancement: optional grouping of file sequences in output

Something that I think would be very helpful for lsd is to be able to group file sequences in a folder.

In other words, say you have:

frame.001.png
frame.002.png
frame.003.png
...
frame.120.png
frame.121.png

Then maybe it could show as one row, perhaps like:

drwxr-xr-x alan alan 4.0 KB Tue Jan  4 15:14:52 2022  .
drwxr-xr-x alan alan 4.0 KB Thu Dec 23 12:06:00 2021  ..
.rwxr-xr-x alan alan  10 MB ------------------------  frame.[001-121].png

Ideally:

• off by default to avoid confusion,
• with a setting to toggle grouping sequences all the time.
• It would also need to not display a file date since it would make no sense,
• but perhaps it could display the total size of the sequence since that information is available already.

If one wanted to contribute such a feature, where in the code would you advise a newcomer to this codebase to look at? 🤔

No files, tests, or entry points are named in the issue. Begin by tracing lsd's output path and configuration handling; the requested behavior still needs a design covering opt-in grouping, dates, and sequence size before implementation can be considered done.
