Update to 26.1

[Gegy]

A first pass at a port to 26.1 - if this is something you already had plans for/had in progress, please feel free to close and ignore! 🙂

Given the larger changes in Vanilla with regards to material definitions/render layer selection, it might warrant larger breaking API changes - but generally I took the path of least resistance here. Hopefully it's a helpful starting point at least! 🙂

In particular, want to highlight:

• Removing render_type fields from model definitions - this seems superseded by Vanilla automatically determining render layer by texture contents - likely needs updates to the wiki
• Removing SpriteIdentifier from the API surface, and replacing with Vanilla Material - not sure the policy for breaking changes like that :)
• Removing ConnectionPredicate resolution for generated extruded item models - it didn't seem to be an intentional feature, but could be misjudging :)

Based on #231, the bug became a lot more obvious with the updated injection point (no breaking overlay would need to be rendered for the bug to be triggered)

I've tested on a surface level with the official Fusion packs, though being not super familiar with all the features it's entirely likely that I have missed some things. :D

Ah sorry, yeah I do already have 26.1 versions of Fusion. I already have and am still refactoring almost the entire mod, hence I haven't released anything yet and it will probably still be a bit.
I do appreciate your effort though, although unfortunately it likely won't be of that much use to me at this point 😅

... not sure the policy for breaking changes like that :)

Yeah between Minecraft versions breaking changes are usually unavoidable, but mods would already need to update for Minecraft's own changes anyways.
I am also sure I probably broke any mod using Fusion's API with the changes I am working on. Unfortunately, I just made parts of the mod into API when they really shouldn't have been. Since I had to make breaking changes anyways for new features in Fusion, I am taking the opportunity to just rework all of it.

Removing ConnectionPredicate resolution for generated extruded item models - it didn't seem to be an intentional feature, but could be misjudging :)

Theoretically, it would just work the same as for any other model, although, indeed, I doubt anyone is going to use an extruded item model for a block.
The model baking part was quite a mess and is what I am currently working on. Hopefully, it should be a lot nicer with all my refactors.

Ooh nice, that's great to hear! :D
Wishing you the best of luck with the refactoring - it certainly doesn't seem like an easy task. 😅
