OrderedDict in Python 3.12+

[McSinyx]

Since Python 3.7, dictionaries are ordered, rendering OrderedDict obsolete. Since Python 3.12, the representation of OrderedDict changes, making the following doctest fail.

hjson-py/hjson/__init__.py

Lines 10 to 11 in 9351a27

	>>> hjson.loads(text)
	OrderedDict([('foo', 'a'), ('bar', 1)])

Got: OrderedDict({'foo': 'a', 'bar': 1})

I hit this problem on FreeBSD running the tests using Python 3.12.
