A JSONDecoder that parses some ISO datetime strings to datetime objects.
Important note: the "some" is because we seem to only be able extend
Python's json library in a way that lets us convert string values within
JSON objects (e.g. '{"lastModified": "2019-07-25T14:35:51"}'). Strings
outside of JSON objects (e.g. '"2019-07-25T14:35:51"') will not be passed
through our decoder.
(N.B. This will override any object_hook specified using arguments to it,
or used in load or loads calls that specify this as the cls.)
