cs_kunar map for CSS v89

I present to you an interesting css map that was ported from the steam workshop. The structure of the cs_kunar map has been completely preserved, only a few minor changes have been made to improve the gameplay on the location. The map itself is a complex and difficult terrain, where the special forces will have to free the hostages. Cs_kunar is an excellent map for snipers and those who like to fight against sniper rifles.
