Organisation public data - adds flags to API

#180

Adds flags to API only

Ideally would add to other data sources - eg spreadsheet downloads
But there is no current place in code to easily do that

can't add to updatedata.py as we are at risk of introducing a circular update path
(we would need to make updates to projects & pipelines also update orgs
but updates to orgs can already also update projects!)

Adding to API for now, as this satisfies immediate user need:
