Added takewhile_inclusive

Issue reference

#730

Changes

I've added the takewhile_inclusive function and tests for it.

I ran the entire test suite and all the tests passed except for one:

======================================================================
FAIL: test_zero_limit (tests.test_more.TimeLimitedTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "D:\github\more-itertools\tests\test_more.py", line 3919, in test_zero_limit
    self.assertEqual(actual, expected)
AssertionError: Lists differ: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,[760707 chars]8982] != []

First list contains 108983 additional elements.
First extra element 0:
0

I wasn't sure how to fix it so I left it alone. I'm on Windows 11. Python 3.10.6.

Please let me know if you'd like me to make any changes. Thank you!

Could you fix this flake8 error?

./tests/test_more.py:5432:80: E501 line too long (81 > 79 characters)

Thanks for the PR!

Done.

I saw the black 3.8 error. I formatted the code with black using the settings in your pyproject.toml file. I hope it works!

Trying again with:

python -m black more_itertools/more.pyi -t py37 --line-length=79 -S
python -m black tests/test_more.py -t py37 --line-length=79 -S

Fingers crossed.
