[PAID/FREE] Reporting on how many posts/threads are created by staff vs users

[mmiodek]

Version
2.0.19

Description
We would like to have improved forum reports/statistics showing how many posts and threads are created by staff (specific group) vs users (another group/groups). We would like to count them and be able to specify a time range (e.g. 2022 only or last 6 months). 
(this request is based on this thread: https://www.simplemachines.org/community/index.php?topic=583495.0 )

Permissions
This would be accessible only to our admins.

Feature Set
I think all requirements are listed in the Description, we can always discuss further details if anything is missing.
