  1. MAINT: save the npz file for pywt.data.nino with a recent numpy 

    This fixes the following warning:

UserWarning: Reading `.npy` or `.npz` file required additional header
parsing as it was created on Python 2. Save the file again to speed up
loading and avoid this warning.

  2. TST: save Matlab compatibility test data with a recent numpy version 

    To do so, it's necessary to actually load the data like this:
```
>>> import numpy as np
>>> a = np.load('dwt_matlabR2012a_result.npz')
>>> keys = list(a.keys())
>>> vals = [a[key] for key in keys]
>>> d = {key:val for key, val in zip(keys, vals)}
>>> np.savez('dwt_matlabR2012a_result.npz', **d)
```
