Fix covid_hosp state_daily

[krivard]

covid_hosp state daily has been failing since June 17 with the following error:

Traceback (most recent call last):

KeyError: "None of ['reporting_cutoff_start'] are in the columns"

This suggests the file format changed for state daily. Indeed, there's a line on the state-daily healthdata.gov site that says the name of this column is now date:

We should:

• [ ] Figure out exactly which date the format change was made (the screenshot above claims June 26 but the traceback above occurred on June 17)
• [ ] Update the code to use date for files posted on or after that date, and reporting_cutoff_start for files posted before that date
  • or maybe check to see if date is present and if not use reporting_cutoff_start instead?

the last file to use reporting_cutoff_start is 6xf2-c3ie_2023-06-16T01-05-09.csv the first file to use date is 6xf2-c3ie_2023-06-16T12-07-16.csv

both were published on the same day. in fact, there are 2 files with each version of the column names, with all 4 files date stamped 16 June.

the typo on the healthdata.gov site is that it lists "26" which should be "16"
