Some snapshot tests are failing (EIA API and workflows)

[jdechalendar]

I noticed these failures when working on #20.

• For the three EIA API tests, these look like minor changes of the API, but could also be due to the way the snapshot is being printed. The order of the keys in the json response seems to have changed from when I made the snapshots. Better standardizing the json output could also be the fix if the only difference is the ordering of the keys.
• For the workflow test, this does not fail on the Ubuntu machine I use, but does fail on the OSX one. The failure seems to be due to float precision. A probable fix is to control the precision when printing to the snapshot.

Summary section of pytest output follows.
