devel/py-cykhash2.0.1_1

Release numerous ports to ports@

I've been retired for a few years, and it is unlikely I will be doing
any more scientific computing support in the future.  I have continued
to maintain ~160 ports to the best of my ability, mainly as a favor to
the community, but I can no longer justify the time and effort
required.  I am therefore releasing most of my scientific ports, along
with a few others, to ports@.  I will continue to maintain ports I am
actively using and those for which I am upstream.

python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.

Updated port-create script to prevent a recurrence

devel/py-cykhash: Cython equivalent to khash-sets/maps

Cykhash is a cython equivalent to khash-sets/maps, efficient
implementation of isin and unique

Benefits:

    Brings functionality of khash to Python and Cython and can be used
    seamlessly in numpy or pandas.

    Numpy's world is lacking the concept of a (hash-)set. This
    shortcoming is fixed and efficient (memory- and speedwise compared
    to pandas') unique and isin are implemented.

    Python-set/dict have big memory-footprint. For some datatypes the
    overhead can be reduced by using khash by factor 4-8.
