Add location for each coop and a map with all coops

[areq]

The full-size map could be displayed at: https://coophub.io/map

[pbrudnick]

is this still a requirement? If so, it should be well described here and un-assigned @MJoaaquin

Agreed, it's a nice feature to have, but outside of scope for now. Proceeding with unassignment and back to "to-do" status.
