Support `conda` feedstock jax wheels

There are community-driven wheels for jax and jaxlib with GPU support via conda-forge

I managed to get a working installation of jax on with only conda installed (no cuda or cudnn prior installation) using

$ conda create -n condajax python=3.9
$ conda activate condajax
$ conda install jaxlib jax --channel conda-forge

It is interesting to see if this works under windows, to avoid using the WSL or building jax from scratch

@djps FYI, not sure if you want to give it a try.

I don't have a Windows with CUDA machine at hand now, but will test this out as soon as I can

I tried this but had conflicts between the version of cuda I have and the version it wanted to install
