Add new command: csdm_active

[SergeyShorokhov]

Bro can you add a small feature in your csdm reapi?
Like amx_csdm 1/0

When 1 --> csdm on
0 --> csdm off

Without restarting the map

I wanted to use your plugin when there are less players in server.
But the issue happens that all plugins get paused but map cleaner plugin doesn't get paused, like even if its paused c4 n everything doesn't work on particular map

Recsdm has a option of enable disable
csdm_active 0/1

Can you add such in your plugin? Please
