Feature: spatial attribute on all resources and collections

[davemfish]

Fixes #93

• Collections get a spatial attribute based on the spatial properties of items within.
• non-spatial resources like tables, archives, get a spatial: null attribute by default, which can be set to an instance of models.SpatialSchema by the user if they wish.

Looks good to me, thanks!

This looks great to me! To confirm, this allows for manual entry of a spatial field for tables and archives, correct?

Yes, there is a set_spatial() method on tables and archive resources, so you can set it that way. Or of course editing the text file is always possible. I imagine a typical case would be setting the spatial fields to be the same as another spatial dataset, so there will be an example in the readme of that:

table_resource = geometamaker.describe('foo.csv')
raster_resource = geometamaker.describe('foo.tif')
table_resource.set_spatial(raster_resource.spatial)
# or
table_resource.spatial = raster_resource.spatial

The individual attributes of spatial are immutable, so this will not work:
table_resource.spatial.bbox = [1, 2, 3, 4]

This is great! Thank you.
