fixed utils.printoptions

FloatFormat was marked as deprecated in numpy 1.14.0 and its deprecation expired in numpy 1.18.0.

Furthermore, FloatingFormat.__call__ takes only 2 positional arguments so it would crash when passing strip_zeros.

After a quick grep in the files, turns out that nor printoptions(True, **kwargs) nor printoptions(strip_zeros=True) was used anywhere, therefore the keyword was removed.

This now works with numpy 1.22.4.
