Map Aardvark.dct_spatial_sm to Locations@kind="Place Name"

Why these changes are being introduced:
* Support place names for location-based searching

How this addresses that need:
* Update MITAardvark.get_locations field method to use 'dct_spatial_sm'

Side effects of this change:
* None

Relevant ticket(s):
* https://mitlibraries.atlassian.net/browse/GDT-217
