Real Traffic Density and Ratio ATS 1.35.e Mod

Changelog v1.35.e:

-reduced slow vehicles to minimum on normal roads

-increased slow on forest/farm roads

-reduced overall max_count for Ai vehicles (density not affected)

this update is to make better use of the slow vehicles, there should be seen very rarely now on the roads, and more on those country roads not open for traffic . the max_count reduction could help with keeping relatively low traffic count and therefore lower amount of data in RAM. Ai density is not affected
