Some numpy.random signatures changed in numpy-1.25.x, and pythran normally wants to warn about those. It's not clear, however, whether or not the numpy changes will be reverted. Until we know, pythran-0.14.0 has a special case to ignore the warnings for numpy.random. Here we ignore those warnings in the doctest parser as well, allowing older versions of pythran to be used with numpy-1.25.x.
One of the tests for the "Computational Math..." book is plotting lines on a vector field by calling scipy.integrate.odeint repeatedly. This test runs, y = integrate.odeint(f, k, t) p += line(zip(t, flatten(y))) in an attempt to flatten y, which is returned as a numpy array of 1-dimensional numpy arrays. However, flatten() isn't smart enough to handle that: it returns a list of 1-dimensional numpy arrays rather than a list of floating point numbers. And numpy-1.25.x now warns about casting 1-dimensional arrays to float deep in our plotting infrastructure. Instead, we now call y.tolist() before passing it to flatten(), and this does the right thing.

Fixes two doctest failures with numpy-1.25.x. One is a warning from pythran that needs to be hidden (to avoid requiring a bleeding-edge version of pythran), and the other is a buggy doctest that now triggers a numpy warning.
