This PR updates coverage from 5.1 to 5.2.1.

Changelog

5.2.1

----------------------------

- The dark mode HTML report still used light colors for the context listing,
making them unreadable (`issue 1009`_).  This is now fixed.

- The time stamp on the HTML report now includes the time zone. Thanks, Xie
Yanbo (`pull request 960`_).

5.2

--------------------------

- The HTML report has been redesigned by Vince Salvino.  There is now a dark
mode, the code text is larger, and system sans serif fonts are used, in
addition to other small changes (`issue 858`_ and `pull request 931`_).

- The ``coverage report`` and ``coverage html`` commands now accept a
``--precision`` option to control the number of decimal points displayed.
Thanks, Teake Nutma (`pull request 982`_).

- The ``coverage report`` and ``coverage html`` commands now accept a
``--no-skip-covered`` option to negate ``--skip-covered``.  Thanks, Anthony
Sottile (`issue 779`_ and `pull request 932`_).

- The ``--skip-empty`` option is now available for the XML report, closing
`issue 976`_.

- The ``coverage report`` command now accepts a ``--sort`` option to specify
how to sort the results.  Thanks, Jerin Peter George (`pull request 1005`_).

- If coverage fails due to the coverage total not reaching the ``--fail-under``
value, it will now print a message making the condition clear.  Thanks,
Naveen Yadav (`pull request 977`_).

- TOML configuration files with non-ASCII characters would cause errors on
Windows (`issue 990`_).  This is now fixed.

- The output of ``--debug=trace`` now includes information about how the
``--source`` option is being interpreted, and the module names being
considered.
