- Included content from US Car Culture v2.3

- Compatibility updated for Jazzycat's AI Traffic v16.6.3.

Relocated (commercial) vans and few other duty vehicle to proper traffic storage to adapt to the new change in v2.2, preventing them from spawning too much:
+ Ford Transit, GMC Savana and GMC Vandura are relocated into truck_light storage.
+ Ford F250, F350, Ford F450, Ram 2500, and Ram 3500 are relocated into truck_medium storage.
+ Mercedes-Benz Metris and Sprinter are relocated into car_custom storage.
+ All 25+ years old vehicles have also been moved to car_custom storage to simulate the classic storage like RTD Edition. I just noticed it wasn't save when I did this before, but here it is now.

As mentioned in the update, all vehicles that are relocated will now follow the spawn rules from the new storage.

- Compatibility updated for v1.55
- Included update from US Car Culture v2.2

Fix bug that make vehicle not spawning again (in Canada and Mexico map mod this time)
