ATS - US 24 Extension

High Poly roads/terrain has been kept from version 1.3.3.

Reduces road terrain size from 1000m to 400m.
Added trees either side to hide the “void” as it’s a shorter terrain.
Reduced length of several “terrain” pieces that were hidden under the map, these are unnecessary as they are too long, and just take up extra resources.

I cannot guarantee this will completely fix the low FPS that some users reported, but it should help a little bit.

Support for 1.46
