warning
Scanning dicts instead of strings is a breaking change. Previous versions
of the SDK accepted a list of strings for scanning. We now require users
to pass in a list of dicts instead. nightfall.scan(['string']) should
now be nightfall.scan([{'id': 'string'}]). This allows you to keep
track of the reference of where the string came from for further processing.
