Print Json in pretty format.
    There's a standard module pprint, can pretty print python dict and list.
    But it doesn't support sorted key. That why we need this func.

    Usage::

        >>> from weatherlab.lib.dataIO.js import prt_js
        >>> prt_js({"a": 1, "b": 2})
        {
            "a": 1,
            "b": 2
        }
