+OrderedDict loader/dumper is implemented, allowing to keep items order when
+loading resp. dumping a file from/to an OrderedDict (Python 3.8+: Also regular
+dicts are supported and are the default items to be loaded to.  As of Python
+3.7 preservation of insertion order is a language feature of regular dicts.)
