py-more-itertools: update to 7.2.0.

7.2.0
-----

    * :func:`distinct_combinations`
    * :func:`set_partitions` (thanks to kbarrett)
    * :func:`filter_except`
    * :func:`map_except`

7.1.0
-----

* New itertools
    * :func:`ichunked` (thanks davebelais and youtux)
    * :func:`only` (thanks jaraco)

* Changes to existing itertools:
    * :func:`numeric_range` now supports ranges specified by
      ``datetime.datetime`` and ``datetime.timedelta`` objects (thanks to \ 
MSeifert04 for tests).
    * :func:`difference` now supports an *initial* keyword argument.

* Other changes
    * Various documentation fixes (thanks raimon49, pylang)

7.0.0
-----

* New itertools:
    * :func:`time_limited`
    * :func:`partitions` (thanks to rominf and Saluev)
    * :func:`substrings_indexes` (thanks to rominf)

* Changes to existing itertools:
    * :func:`collapse` now treats ``bytes`` objects the same as ``str`` objects. \ 
(thanks to Sweenpet)

The major version update is due to the change in the default behavior of
:func:`collapse`. It now treats ``bytes`` objects the same as ``str`` objects.
This aligns its behavior with :func:`always_iterable`.

.. code-block:: python

    >>> from more_itertools import collapse
    >>> iterable = [[1, 2], b'345', [6]]
    >>> print(list(collapse(iterable)))
    [1, 2, b'345', 6]

6.0.0
-----

* Major changes:
    * Python 2.7 is no longer supported. The 5.0.0 release will be the last
      version targeting Python 2.7.
    * All future releases will target the active versions of Python 3.
      As of 2019, those are Python 3.4 and above.
    * The ``six`` library is no longer a dependency.
    * The :func:`accumulate` function is no longer part of this library. You
      may import a better version from the standard ``itertools`` module.

* Changes to existing itertools:
    * The order of the parameters in :func:`grouper` have changed to match
      the latest recipe in the itertools documentation. Use of the old order
      will be supported in this release, but emit a  ``DeprecationWarning``.
      The legacy behavior will be dropped in a future release. (thanks to jaraco)
    * :func:`distinct_permutations` was improved (thanks to jferard - see also \ 
`permutations with unique values \ 
<https://stackoverflow.com/questions/6284396/permutations-with-unique-values>`_ \ 
at StackOverflow.)
    * An unused parameter was removed from :func:`substrings`. (thanks to pylang)

* Other changes:
    * The docs for :func:`unique_everseen` were improved. (thanks to jferard and \ 
MSeifert04)
    * Several Python 2-isms were removed. (thanks to jaraco, MSeifert04, and hugovk)
