Database change: space_group -> space_group_number
There will be a breaking change to the database. The material column space_group will be renamed to space_group_number.
This change will probably be active in the next production and when we switched to the new ingestion infrastructure. (not the current 32, the one after that). I'll update this issue, if this panning changes.
FYI. There will also be a new column called space_group_international_short_symbol.
