Implement dynamic date format similar to ls (Hour/Year based on file age)

[toshirov]

I would like to request the implementation of a conditional date formatting behavior in lsd, similar to the one provided by the ls command. Currently, ls displays:

If the file is less than a year old: Month Day Hour (e.g., Feb 11 14:35)
If the file is a year old or older: Month Day Year (e.g., Feb 11 2023)

This behavior is very useful to differentiate between recent and older files, especially when managing directories with a large number of entries.

Proposed Functionality:

Add an option that allows lsd to automatically choose between two date formats based on the file's age:

If the file is less than a year old, use %b %d %H:%M.
If the file is a year or older, use %b %d %Y.
