v2.3 Release

*Note: This is the first part of a new rework progress, which will primarily focus on Jazzycat's AI Traffic pack addon

1. Model Spawn Rate Overhaul - Part 1
- Removed spawn rate based on model year, as this is proven to be inaccurate when I look through sales data, with many models having higher sales in their early generations.
- Removed spawn rate based on non-luxury/luxury brands; this is now obsolete and will be decided primarily by sales figures instead.
- Reworked all traffic storage; all non-commercial vehicles will now be categorized into 3 levels.
+ Common traffic (For common brands/models)
+ Rare traffic (For rare brands/models)
+ Extremely rare traffic (For extremely rare brands/models)
- Disabled spawn for some additional models.
- Disabled all GMC Savana variants that have Canadian logos in US.

2. License Plate Expansion
- Coherent Series/Models spawning: All standard series spawning have been adjusted, based on which year the vehicle model was produced and sold, it will tend to spawn with the most common series during that time.
- Muscle/Sport class vehicles will now have a much higher chance to spawn with vanity plates, showcasing their luxurious and fashionable appearance by using custom plates more.
- All out-of-state vehicles from Mexico have been reworked to choose a more accurate and more common one from Jazzycat's AI Traffic Pack.
- All U-Haul trucks will now spawn with Arizona plates, just like in real life.

3. Parked Vehicle Rework
A new mini feature aims to improve this aspect to better reflect the immersion for the stationary vehicles' spawn rate. Parked vehicles will now be categorized into 5 different levels to match the new spawn rate rework, as follows:

- COMMON PARKED (Used for most common brands like Ford, Chevrolet, Toyota, Honda, etc, and their common model).
- UNCOMMON PARKED (Used for less common brands like Mazda, Subaru, GMC, etc, and their models).
- RARE PARKED (Used for rare brands like Acura, Dodge, Cadillac, etc, and their models).
- EXTREMELY PARKED (Used for extremely rare brands like Jaguar, Maserati, etc, and their models).
- CLASSIC/ANTIQUE PARKED (Will be fully used after v2.4)

Full changelog:
https://forum.scssoft.com/viewtopic.php?p=2049833#p2049833

- Added superstructure_truck_work.sui from 1.55 for them to spawn in traffic (New Municipal Truck variant)
- Added files from add-ons to prepare for more files merging between add-ons and main mod, which help reducing repetitive files that need to be loaded.

- Fixed missing parked model bug for all Mack RD garbage truck variants.
- Ford Crown Victoria Taxi's wheel rim has been changed from white to black, like the majority of them in real life. Thanks Drive Safely for the suggestion.

Relocated (commercial) vans, caravan, and some special vehicles to proper traffic storage to adapt to the new change in v2.2, preventing them from spawning too much:
+ Ford Transit, Chevrolet City Express, and Chevrolet Express are relocated into truck_light storage.
+ Ford Super Duty - Dominator is relocated into truck_custom storage.
+ Chevrolet G20 Conversion Van and Frelightiner Solera is relocated into car_custom storage.

As mentioned in the update, they will now follow the spawn rules from the new storage.

- Hotfix to remove unnecessery .sui file reference were accidently left behind
