Load setuptools configuration from ``setup.cfg`` files.

**API will be made private in the future**

To read project metadata, consider using
``build.util.project_wheel_metadata`` (https://pypi.org/project/build/).
For simple scenarios, you can also try parsing the file directly
with the help of ``configparser``.

    [options.extras_require]
    foo = bar;python_version<"4"

    It looks like one requirement with an environment marker
    but because there is no newline, it's parsed as two requirements
    with a semicolon as separator.

    Therefore, if:
        * input string does not contain a newline AND
        * parsed result contains two requirements AND
        * parsing of the two parts from the result ("<first>;<second>")
        leads in a valid Requirement with a valid marker
    a UserWarning is shown to inform the user about the possible problem.
