setup.py imports numpy

[mliberty1]

The setup.py script imports numpy which prevents joulescope from installing on clean systems. To duplicate (macOS Mojave 10.14.5):

virtualenv {path}
. {path}/bin/activate
pip3 install -U --no-cache-dir joulescope

Gives

(joulescope) achilles:pyjoulescope_ui mliberty$ pip3 install -U --no-cache-dir joulescope
