[ATS] Doubles/Triples/Heavy Trailers in Traffic V1.0 [1.30.x]

This is an add-on for Real Traffic Density and Ratio by Cip v1.6 the add-on is bringing in traffic all doubles, triples and heavy trailers from the Heavy cargo DLC in traffic. because traffic density files requires modifications, this add-on will only work with my traffic density mod and only with latest version thank you Mr Larrington for implementing the doubles and triples in ATS, I only created the traffic spawn for them. for Heavy cargo in traffic thanks to Jazzycat for his old mod that I adapted for 1.30, to the new traffic system. all trailers are free to circulate in all States.
