[MAP] [Config] Security Officer Scaling @ Round-Start

Intended for high-population servers

Open security officer positions scale with population, between 5 slots at ~40 players to 12 slots at ~96 players

Default coefficient is 8, but may be modified (or disabled) in the config.

Extra lockers will spawn if there aren't enough lockers.
So if there are only 10 people joining the round, when 40 more people join mid-round there won't be enough officers.
