Integrate new hospital data source

[patricksheehan]

HHS now has an API with hospitalization data. The scope of this issue is to replace our BI connector with a connector for this data, and to ensure that all transformations match (i.e. column names are correct and data format is correct)

ICU:
https://protect-public.hhs.gov/datasets/hhs-protect-percentage-of-icu-beds-occupied-estimate/data?geometry=21.717%2C-16.702%2C-28.556%2C72.161

Inpatient:
https://protect-public.hhs.gov/datasets/hhs-protect-percentage-of-inpatient-beds-occupied-estimate/data?geometry=74.803%2C-16.702%2C-81.642%2C72.161

This issue can be completed at the same time as

#22 and #21, so please feed three birds with one hand on this one!
