Newest version si not compatible with python 3.12

[wassupxP]

Hello,
even though readme mentions that the package is available for python 3.12 as well, it always fails as distutils package is removed from python3.12. I tried to create pull request, but couldn't.

Solution 1 - external dependency, packaging, also dependency of pytest:

try:
    import xdist
except ImportError:
    pass
else:
    from packaging.version import Version
    xdist_version = Version(xdist.__version__)
    if xdist_version >= Version("1.14"):

Solution 2 - without external dependency

try:
    import xdist
except ImportError:
    pass
else:
    def versiontuple(v):
        return tuple(map(int, (v.split("."))))

    if versiontuple(xdist.__version__) >= versiontuple("1.14"):
