chore: Consolidate logger setup and add better handling of packets (#1389)

Browse Source 
* Logger to Server class

Dont handle master packets from our clients

* move to namespace

Revert "remove extra headers"

This reverts commit ac7b901ece22165cdb0f38fca4be7d8fdf004de8.

remove extra headers

no changes otherwise.

* Merge branch 'main' into server_consolidation_of_work

* Update WorldServer.cpp

* fix submodule version
