Windows seems to run numpy on int32?

[michaeldeistler]

My student @dorimolnar runs Jaxley on Windows and is having issues because the following instantiates a np.int32 array:

import numpy as np
np.asarray(0).dtype

On linux and on Mac, this instantiates a np.int64 array. Here, we assume int64. This assumption then causes assertion errors here.

We should try to make this assert more robust to avoid issues on Windows or small laptops which might default to single precision instead of to double precision.
