py-more-itertools: updated to 9.0.0

9.0.0
------

* Potentially breaking changes
    * :func:`grouper` no longer accepts an integer as its first argument. \ 
Previously this raised a ``DeprecationWarning``.
    * :func:`collate` has been removed. Use the built-in :func:`heapq.merge` instead.
    * :func:`windowed` now yields nothing when its iterable is empty.
    * This library now advertises support for Python 3.7+.

* New functions
    * :func:`constrained_batches`
    * :func:`batched` (from the Python itertools docs)
    * :func:`polynomial_from_roots` (from the Python itertools docs)
    * :func:`sieve` (from the Python itertools docs)

* Other changes
    * Some documentation issues were fixed (thanks to nanouasyn)
