Issue details

There is a discrepancy between the numbers reported on the King County website: https://kingcounty.gov/depts/health/covid-19/data/daily-summary.aspx and the numbers reported on the atlas. For example, on the county website, 05/15 reports 7462 cases, whereas the datascraper reports 7325.

I looked into it a bit, and it looks like King County back-updates their cases -- e.g., every day, new data are added for both that day and updated for all previous days. This might be the source of the discrepancy.
