Add more process information to mac.pslist plugin

[cpuu]

Enhance the macOS PsList plugin by including additional process information such as offset, UID, GID, and start time in the output. Update the TreeGrid columns to display the new information.
(I have arranged the output format and order of this plugin to be in line with the existing Volatility2.)

Before

$ python3 vol.py -f ../contact_me mac.pslist.PsList
Volatility 3 Framework 2.4.2
Progress:  100.00               Stacking attempts finished
PID     PPID    COMM

0       0       kernel_task
1       0       launchd
35      1       UserEventAgent
38      1       kextd
39      1       fseventsd
37      1       uninstalld
45      1       configd
46      1       powerd
52      1       logd

After

$ python3 vol.py -f ../contact_me mac.pslist.PsList
Volatility 3 Framework 2.4.2
Progress:  100.00               Stacking attempts finished
OFFSET          NAME            PID     UID     GID     Start Time                      PPID

All right, I left a few comments on this change.
I don't know if the maintainer will agree with my review, but it would be good to think about it.

I apologize for the delayed response. I have just completed the changes you suggested. Some of the suggestions were applicable and have been implemented, while others fell outside the scope of this specific proposal. I will address those suggestions separately in a future Pull Request to ensure consistency across the project. Thank you for your understanding and valuable feedback.
