SCS Lowloader Hidden Cargo Unlock [1.41.x]

What it adds:
4 axle long LOWLOADER: Vossloh Locomotive 62t
4 axle short LOWLOADER: Concrete beams 51t
4+1 axle short LOWLOADER: Concrete beams 51t
4+1 axle short LOWBED: Concrete beams 51t
5 axle short LOWBED: Concrete beams 51t

These cargoes are in the base game but SCS chose to hide them for some reason (probably realistic axle weight restrictions)
REQUIRES HEAVY CARGO DLC
