Labro Z22 deco

Labro Z2 had issues because too many objects were packed into a single texture space. Because of this, the washroom has complete black texture and other texture errors. To improve the overall texture quality, I removed the top floor in Z22, carefully rescaled and repositioned the texture layout based on each part's visibility and importance, and reduced unnecessary or hidden polygons. These optimizations resulted in a cleaner model with a more polished and efficient texture layout in the Labro Z22 deco model.
