feat: Allow custom CS# directory for flexible server deployment (aka. css_basepath)

[ELDment]

#117 #391
This implementation relies on command line parameters (startup arguments) rather than ConVar, which introduces certain limitations. The value must be set when starting the CS2 server and cannot be changed afterwards. If not set or if the specified directory does not exist, the default value /addons/counterstrikesharp will be used

cs2.exe -dedicated -console +css_basepath "/addons/counterstrikesharp2" +game_type 0 +game_mode 1 -maxplayers 10 +mapgroup mg_active +map de_dust2  -high -port 27020 -ip 0.0.0.0

OR

cs2.exe -dedicated -console +css_basepath addons/counterstrikesharp3 +game_type 0 +game_mode 1 -maxplayers 10 +mapgroup mg_active +map de_dust2  -high -port 27030 -ip 0.0.0.0

The parameter must be +css_basepath (with plus sign)

btw: Path separators will be automatically normalized (mixed \ and / are supported)

Currently working as expected on Windows platform. Haven't tested on Linux yet

Well, I'm not sure if this feature is actually needed, but honestly I don't know any other way to run multiple CS# instances on the same server installation without having to download separate server files for each instance

I believe you can use the same base with symlinks to run multiple instances

the code is LGTM however I don't have any linux environment to test there as well at the moment.

Sorry, quick question, what's symlinks?
