* Repo-Copy the Pillow 6.2.2 release to graphics/py-pillow6 to retain
backwards compatibility for Python 2 consumers as the Pillow 7.0.0 release
dropped the support for Python 2.
* Apply conditional statements to use either Pillow 7.x or Pillow 6.x for
consumers that can be built for Python 2 or newer.
* Exceptions are ports that can be built only for either Python 2 or
Python 3. For the first case, consumers are just assigned to the
repo-copied graphics/py-pillow6.
* Also remove Pillow from BUILD_DEPENDS of math/py-PyWavelets as it is not
listed in setup.py as a build dependency [1] and relax the version
requirements of Pillow for www/py-wagtail.
