use RESP-NET to retrieve FluSurv-NET hospitalization data #214
Description
currently the get_cdc_hosp() function gets FluSurv-NET via the hospitalizations() helper, which queries the FluView API.
the FluSurv-NET hospitalization data is now reported through RESP-NET, which is accessible via API: https://data.cdc.gov/Public-Health-Surveillance/Rates-of-Laboratory-Confirmed-RSV-COVID-19-and-Flu/kvib-3txy/about_data
we should consider pulling the FluSurv data from the RESP-NET API, which appears more intuitive overall and seems to be easier to manage geographic resolution ... plus RESP-NET includes COVID-19 and RSV data, which we could potentially make accessible via options to the data retrieval function
