Transform USAFacts Case Data to look like NYTimes Data

[lossyrob]

Currently we have live case data coming in from NYTimes and USAFacts in two different formats. The NYTimes has each row represent a date for a region (either state or county). The USAFacts data is transposed of that, having each row be the region and columns for each of the dates.

The goal of this issue is to do transformations on the USAFacts data in the methods that fetch it in covidcaremap.cases so that it produces the same format data as the NYTimes data. There are multiple places in the codebase that already use USAFacts that would need to be updated.
