Status of Flux model zoo

Given the post by Chris https://discourse.julialang.org/t/zygote-error-only-reference-types-can-be-differentiated-with-params/38224/5, it seems that a SciML zoo would be more appropriate.

I’d interested in participating.

This is also of interest for inclusion: https://github.com/GdMacmillan/ml_flux_tutorial on how to use Julia on Google Colab.
