cap the likert score at 5. This was happening already at the scraper
level but it's also now being done by the admin data loader for safety.
Also make sure to just update admin data instead of deleting and
reloading all values each load. Add tests to confirm this behavior
instead of hard coded values. Produce a clean csv and a csv with all
the removed values and columns with reason for removal. Add script for
running cleaning for each project
