KI LKW EXPANSION [1.39.X]

The simple goal for this mod is to expand the default SCS AI Truck traffic, using stock SCS parts and hopefully at mininal FPS cost.

Currently this mod includes:
7 Freightliner Cascadia varients
2 Kenworth T680 varients
2 Peterbilt 579 varients
2 Volvo VNL varients

The mod also expands the color options for the trucks above, as well as modifes the spawn rate for daycab W900s, 389s and Lonestars. Making them more rare, reasoning being is that in real life these configurations aren't that commonly seen on US roads. I may tweak them in the future.
Do note: This mod modifies the stock AI truck traffic definition files, any mods that also change those files will be overwritten/overwrite (depending on load order) the files, meaning that the vanilla SCS trucks might not have my changes applied.
