[Fabric] Change to ClassFileTransformer implementation

[Kasualix]

Mixins are way less effective/compatible than ClassFileTransformer for Redirector.

Currently investigate how to register the transformer

Fabric use launchwrapper, so use ITweak

I was referring to this class earlier.

So if we create a transformer impl ITweaker like FabricTweaker, how can we register it and get it loaded into mc somewhere?

use Launch.classLoader.registerTransformer in some early stage. ITweak is a early stage, but not the only one.
You could ask fabric for help. Find out how to create a coremod.
I am concerned that coremods are not supported, since fabric is built in mixin.(x
