Build is broken for py38

The Travis build is broken for py38.

there is a time out for the build.. all dependencies seem to be installed w/o a problem, so it will take a bit of sleuthing

I have verified that the tool works for py38, just as an FYI. so my thinking is that this is just in the travis yml

the code at present shows all recent storms, incl Hx Delta and Hx Zeta — solving #200 .
This version of the code is not yet on PyPI, but can be used by installing directly from GH.. via e.g., :

pip install git+https://github.com/UNCG-DAISY/psi-collect
