initialized with a season, i.e. "2024-25 Fall". Update scapers for
admin data, enrollment and staffing to use the new range standard
correctly. Update the loaders for admin data, enrollment and staffing
so that it populates all seasons in a given year. So admin data for
2024-25 gets loaded into "2024-25 Fall" and "2024-25 Spring". Add tests
for the new range format. Set the default cutoff for the start of Spring season will be the last Sunday in February
to survey table. We no longer check or keep track of the survey type.
Instead we look in the database to see if a survey item has at least 10
responses. If it does, that survey item was presented to the respondent
and we count it, and all responses when calculating the response rate.
Remove response rate timestamp from caching logic because we no longer
add the response rate to the database. All response rates are calculated
on the fly
Update three_b_two scraper to use teacher only numbers
swap over to using https://profiles.doe.mass.edu/statereport/gradesubjectstaffing.aspx as the source of staffing information
