np.stack error on complex numpy array

[damienjacquet]

to encode complex array, the np.stack method is used, but it results in the following error :

File "C:\XXX\Lib\site-packages\jdata\jdata.py", line 136, in encode
newobj["_ArrayData_"] = np.stack(d.ravel().real, d.ravel().imag)
TypeError: only integer scalar arrays can be converted to a scalar index

imaginary part is seen as the "axis" parameter of np.stack function. adding 2 parenthesis should fix the bug
newobj["_ArrayData_"] = np.stack((d.ravel().real, d.ravel().imag))
