Python 2 compatibility

In general, fmriprep has dropped support for Python 2. But we will keep some good practices to make it easier for potential contributors to send PRs with compatibility code:

• New files: declare the utf-8 encoding in the header:

  #!/usr/bin/env python
  # -*- coding: utf-8 -*-
  # emacs: -*- mode: python; py-indent-offset: 4; indent-tabs-mode: nil -*-
  # vi: set ft=python sts=4 ts=4 sw=4 et:
  

• New files: first import should be from __future__:

  from __future__ import print_function, division, absolute_import, unicode_literals
