update NNlib and Flux compat

[CarloLucibello]

This package is incompatible with Flux 0.14 and NNlib 0.9. Can the compatibility be updated?

[chengchingwen]

What are the breaking changes beside dropping julia 1.6 and using package extension?

[CarloLucibello]

Just the extension thing. So NNlibCUDA is deprecated, and for CUDA support in Flux one has to explicitly load CUDA.jl

[CarloLucibello]

I think the only required change here is to drop NNlibCUDA and to increase julia compatibility to >= 1.9.

[chengchingwen]

Yes, but I'm a little worried about dropping julia < 1.9.

[CarloLucibello]

Julia 1.9 changed many things. I'm sure those interested in getting package updates are already using it.
On the other hand, it seems more problematic not to get Flux and NNlib updates if you have this package in your environment.

Yes, but I'm a little worried about dropping julia < 1.9.

@chengchingwen can you please elaborate?

[chengchingwen]

@originalsouth Simply because julia 1.6 is the LTS version.

[originalsouth]

I guess most FluxML packages as Flux.jl has dropped that support already... perhaps an LTS branch for this repository can mediate the conflict of interests?

6 months later, any updates on updating Flux compat? I think this is long overdue
