Prototype of dispatched UnbakedModel serializers

[FiniteReality]

Blame @XFactHD for making me work on this :laughing:

This is a prototype of a potential alternative to Neo's current model loading extension to allow custom implementations of UnbakedModel instead of stapling an IUnbakedGeometry onto BlockModel. I've been theorycrafting this for a while, hinting that I wanted to get rid of IUnbakedGeometry and what feels like a bunch of legacy cruft, but this is the first real step in that direction.

Pros:

• No more weird IUnbakedGeometry codepaths
• Simpler* implementation (in my opinion :stuck_out_tongue:)
• Registering custom model loaders only requires registering a codec for a custom subclass
• Parent model references using custom model types Just Work

Cons:

• Codecs slow (Codecs are only used on resource reload, so it shouldn't be TOO bad?)
• More patches (at least until we find a better way to change generic types)
• Slightly harder to maintain (at least until Mojang codec-ifies their own models)

The script works on both *nix and Windows as long as you have the JDK bin folder on the path.
The script will clone the MDK in a folder named NeoForge-pr1557.
On Powershell you will need to remove the -L flag from the curl invocation.

mkdir NeoForge-pr1557
cd NeoForge-pr1557
curl -L https://prmaven.neoforged.net/NeoForge/pr1557/net/neoforged/neoforge/21.1.59-pr-1557-feature-block-models-unbaked/mdk-pr1557.zip -o mdk.zip
jar xf mdk.zip
rm mdk.zip || del mdk.zip
