Bumped version number

adding save_json(filename) and load_json(filename) to save and load from json
it is not recomended to save simulations as json and load them back, this process is destructive to information since json does not keep precise type information like hdf5 does, this is mostly intended as a way to just store the setup in json to simplify some ways of trading simulations around
in general json can be used in addition to hdf5 but never as a replacement
