Add compatibility for Railcraft Reborn

[Edivad99]

Description of the Bug

If you use the 1.16 textures from Railcraft 3D resource pack, then most work (straight rails, turns, elevating rail), but the ones that climb a block don't work. The vanilla rails work fine so it seems to be an issue with Railcraft Reborn's model (?).

Configuration

- Mod version: railcraft-reborn-1.20.1-1.0.2
- NeoForge/Forge version: Forge 47.1.0 (also tried newest 47.1.10)
- Minecraft version: MC 1.20.1
- Are you playing on a server?: SP, no other mods

To Reproduce

1. load resource pack (after repacking the zip needs to have the assets folder, pack.mcmeta and pack.png in the root of the zip)
2. place rails on ground
3. ones from Railcraft Reborn that climb blocks don't have 3D model

Expected behavior

They should have a 3D model
