NCI Gadi build

Unless using a GPU enabled node, you will need OSMesa

Gadi has a recent enough mesa that uses llvmpipe and no mesa build is necessary!

To install in active environment

LV_OSMESA=1 pip3 install --no-binary :all: lavavu

Or to install for user

LV_OSMESA=1 pip3 install --user --no-binary :all: lavavu
