Document age-stratified data missing in state aggregated files

[jsfenfen]

The facility level file includes variables for the count of admissions stratified by age, e.g. previous_day_admission_adult_covid_confirmed_30-39_7_day_sum. Because data is only shown in the public files when cell size is 4 or greater, these variables are often redacted..

This data would be much more useful aggregated by state. But the state level files omit these variables entirely. I've not seen any explanation for this. This is true for the state level files by day or week.

This data was added to the state-level release on April 30. There's a limited analysis of it here: http://www.jacobfenton.com/analyses/juvenile_covid_03012021/hhs_hosp_trends.html
