Issue with installing lpy on Mac

[hannahwolfe]

Hi,

I was having trouble running lpy because qhull wasn't installed. Here is how I got it working:

Created a conda environment:
conda create --name lpy python=3.9

activated the environment:
conda activate lpy

installed quhull:
conda install qhull

installed lpy:
conda install openalea.lpy -c fredboudon -c conda-forge
