I didn't mean to do this, but it seems like we do want the updated Dyfan Jones?

@Damonamajor don't forget to update dbt documentation with the new table

I had it in the next branch, but happy to migrate it over.

yeah, let's just for the spatial.traffic table.

couple other things for the warehouse script specifically:

• let's recode 0000 in condition year to NA
• look through the code book and see if any other data that should be NA needs to be re-coded
• let's recode stuff like surface_type with the values their numbers correspond to, ie concrete rather than 800 for surface type, if we have that information.
