Allow control characters inside strings.

[ezequielramos]

By the definition of python json loads method:

"""
        If ``strict`` is false (true is the default), then control
        characters will be allowed inside strings.  Control characters in
        this context are those with character codes in the 0-31 range,
        including ``'\\t'`` (tab), ``'\\n'``, ``'\\r'`` and ``'\\0'``.
"""

By some reason, the OCI NoSQL Tables that I'm interacting with has those types of characters registered. So the only way I can get access to it is by using this parameter as False.
