Remove numpy as a dependency (CrayLabs#132)

* Remove np from step.py and requirements

Create a helper function called get_base_36_repr so that we can remove numpy from step.py

Remove numpy from requirements.txt

Pin requirements.dev to a specific version of numpy

* Remove numpy from requirements

* Remove numpy from setup
