Description incorrectly specifies input format as JSON. It's an Object or dict, not a String that has to be parsed.

Remove JSON tag.
The kata is using maps in JS and dicts on Python, JSON are raw strings.

issue part: JS version needs to be completely rewritten to be consistent with the python one

• description corrected (start date was totally wrong...)
• python 3.6 added
• random tests added in python
• replaced fixd tests by more useful ones...
