Create new Json Schemas

[cdesyoun]

@valentinedwv and @aufdenkampe I have created json schema (https://github.com/ODM2/YODA-Tools/blob/master/jsonschema/yoda_timeseries.json) based on timeseries yoda file. Following with this json schema, I use "Valideer" python package (https://github.com/podio/valideer) for data validation.
