[MTR] Shinkansen Infrastructure

• Added catenary frames :
  • HD versions where all the trusses are 3D objects
  • LD version where the trusses are a texture drawn on a single mesh
  • [to be used with freelength catenary cables + extra cables if you want]
• Added double bridge poles: These only need to be applied on one side of a pair of rails, and will stay together in turns rather than get out of sync.

• Added a standalone pole decoration object (should help when the auto placement doesn't cover a certain bit)
• Added a freelength catenary that can cover tight turns (3 block sections instead of 20)
• Added the following pole distances to go with freelength catenary :
  • 5m
  • 10m
  • 20m

The standalone tied-arch bridge is now split into two parts. This is to prevent issues with the bridge disappearing because of Minecraft's occlusion system. This makes setting it up a bit longer, but ensures you can actually go through the bridge and it won't vanish.

Setup :
