Pyarrow version 0.16.0 is not working with test suite

[denver1117]

Describe the bug The test suite cannot import pyarrow (0.16.0) in python 3.5 or python 3.7. There do not seem to be any errors in the installation. Failing travis build: https://travis-ci.org/Ibotta/sk-dist/jobs/648507535?utm_medium=notification&utm_source=github_status Addressed by pinning pyarrow in this PR: https://github.com/Ibotta/sk-dist/pull/36

To Reproduce Steps to reproduce the behavior:

1. Unpin pyarrow in setup.py
2. Run the travis build

Expected behavior Ideally we'd be able to unpin pyarrow in the test suite and regularly test on the most recent version (0.16.0)

Additional context This was revealed when pyarrow released 0.16.0 on 2/7/2020
