Fixes #2417

Appears this failed tests previously due to a permissions error. Attempted to fix in GCP.

Appears I assigned the wrong role in IAM. Trying again.

@anth-volk it's now passing the test- I ran the policyengine.py package locally on the latest versions of the data and pe-us package and it also returned 95.1m, so I think that's the true number we're aiming for. I also added a test for the winner/loser share.
