Removing outdated upload format to avoid confusion
Not really relevant anymore, can use Github issues instead
Bringing over latest changes from "scratch" repository, which I will stop using to avoid confusion
Major changes:

 - using zeros instead of missing rows if no data found
No headers on indicator.csv
