[MTR3/4] CP Lisbon Suburban Trains Pack

Changelog

Added the following features and improvements:

• Separated the bogies from the train bodies on all units, allowing them to rotate independently for more realistic movement, especially on curves.
• Added a modernised CP 2400 Series unit featuring the current post-2013 livery. The original-livery unit (2412) remains available in the resource pack as unit 2412.
• Reduced the triangle count across all trains, with significant optimisations to the 3150/3250 Series.
• Replaced the pantograph on the 3150/3250 Series with a more accurate diamond pantograph appropriate for the unit's operating voltage.
• Added a new pantograph variant for the 3150/3250 Series. These units can now also use the Z-shaped pantograph, as fitted to the real trains since the early 2010s.
• All trains now support two pantograph height variants (5 m and 6 m). Previously, all units were limited to 6 m. This improves compatibility with the MTR Mod's recommended overhead wire height.
• Added exterior destination displays to the 2300, 2400 (including unit 2412), and 3150/3250 Series.
• Added interior passenger information displays to the 2300, 2400 (including unit 2412), and 3150/3250 Series.
• Added Physically Based Rendering (PBR) materials to every train in the resource pack.
• Added new sounds for the 3150/3250 Series to better reflect their real-life counterparts.

Other:

• Minor bug fixes, optimisations, and model improvements.
