Reporting start date for school year 2022-2023 has changed to 2022.08.21. These are to more closely align with student attendance dates.

Added new endpoints for student COVID vaccination rates.

2022.02.24 v0.15:

Modified all in-use endpoints to return timestamps as offsets for date cutoffs with midnight central time, in unified format. The following endpoints are affected: DistrictNoAdmittance, SchoolNoAdmittance, School2021DailyCovidActionable, SchoolWeeklyCovidActionable, District2021WeeklyCovidTesting, District2021DailyCovidTesting
Modified all endpoints in use by cps.edu to use single source for all report totals, rather than force api servers to assemble totals from system of record independently.
Renamed TotalPositiveCount to TotalCaseCount on school daily responses for readability. Both fields reflect same data value, to prevent backward compatibility breakage.
Renamed PositiveCount to TotalCaseCount on District2021WeeklyCovidActionable / District2021WeeklyCovidTesting to reduce confusion on what the value represents.

Added additional detail to multiple endpoint help page descriptions.
Partial week totals are no longer returned from weekly endpoints, to align with CDPH reporting guidelines.
