Facade render rework

[covers1624]

This has been in progress for some time but is finally ready. Basically, this is a complete rewrite of AE's Facade rendering. Myself and @yueh have been in discussion whilst this has been worked on so this isn't just a random PR out of the blue.

So what does this do and why?
AE's facade rendering was extremely simple, it polled the model it wanted to imitate and used the first available texture found, for most blocks this is fine and a adequate solution, where this solution fails is connected textures. This PR Addresses those issues, instead of polling for textures and building a new model, it simply 'slices' the model of the block into the facade shape, re interpolating textures and colours along the way, to do this it utilises a new pipeline i wrote for running multiple transformers across baked quads, its extremely fast and will spit the quad out in the same format that its piped in with, meaning that full bight blocks with CTM should render just fine, but due to the baked model pipeline in minecraft is about as efficient as it gets, Realistically Forge's lighting pipeline when rendering a chunk layer of Dense cables is slower than the pipeline slicing a chunk layer of Facades, in order for the system to get faster i need the ability to pipe each quad into forge's lighter.

Enough chit chat, Screenshots!
Connected textures work across TD Covers too!
(Chisel Block, AE facade, TD Cover, Chisel block)

Edge ZFighting was solved by 'kicking' the edges in.

But only kicking them in when needed.

Works perfectly with 'thin' facades.

Demonstrating that the pipeline respects VertexFormats, base edits to show controllers always active were used for this specifically for the screenshot.

Transparency issues are solved by shrinking the bounds of the transparent facade.

Merging into feature branch to potentially amend/squash (and hope it keeps the author as well as testing the new review service.
