Spanish census data at larger geometries

We only bring it in at seccion censal level right now, but we should provide larger geometries, too.

@michellemho Do you think you could look at the INE site and see if we can track down some equivalent data files at a coarser geographic resolution than seccion censal?

Municipal, provincial and national level data here:

Thanks @michellemho ! These would appear to be the files we'd need, but having looked at them closer the inconsistencies in how they've produced them make me think we shouldn't go forward with getting data from them.

An alternative solution would be to aggregate all the higher-order stuff ourselves. Putting this in the Icebox for now.
