it's impossible to use the latest MLJFlux and MLUtils at the same time; somewhere in the compatibility here we're limiting Metalhead (idk why it's a dependency to begin with)

I guess we're waiting for FluxML/Metalhead.jl#204, so not really an MLUtils issue.

MetalHead is a dependency of MLJFlux because the default ImageClassifier builder uses a MetalHead builder.
