Rolling window price change statistics feture is not implemented

It can be realized by making the following changes in binance.py file at line 4291

            rolling = self.safe_bool(params, 'rolling', False)
            params = self.omit(params, 'rolling')
            if rolling:
                response = self.publicGetTicker(self.extend(request, params))
            else:
                response = self.publicGetTicker24hr(self.extend(request, params))

instead of

response = self.publicGetTicker24hr(self.extend(request, params))
