Windows compatibility

I got the following error when installing through pip on windows 11:

I had to change the setup.py to make it compatible with windows. I had to get rid of the pathlib dependency and change it to os. I did the following:

Clone the repository and change the setup.py to

 import os
import re
import setuptools

def parse_reqs(filename):
    with open(filename, 'r', encoding='utf-8') as file:
        requirements = file.read().split('\n')
    requirements = [x for x in requirements if x.strip()]
    return requirements

def parse_version(filename):
    base_path = os.path.dirname(__file__)
    full_path = os.path.join(base_path, filename)
    with open(full_path, 'r', encoding='utf-8') as file:
        text = file.read()
    version = re.search(r"__version__ = '(.*)'", text).group(1)
    return version

with open('README.md', 'r', encoding='utf-8') as file:
    long_description = file.read()

setuptools.setup(
    name='embodied',
    version=parse_version('embodied/__init__.py'),
    author='Danijar Hafner',
    author_email='[email protected]',
    description='Fast reinforcement learning research',
    url='http://github.com/danijar/embodied',
    long_description=long_description,
    long_description_content_type='text/markdown',
    packages=setuptools.find_packages(),
    include_package_data=True,
    install_requires=parse_reqs('embodied/requirements.txt'),
    extras_require={
        'dreamerv3': parse_reqs('embodied/agents/dreamerv3/requirements.txt'),
    },
    classifiers=[
        'Intended Audience :: Science/Research',
        'License :: OSI Approved :: MIT License',
        'Programming Language :: Python :: 3',
        'Topic :: Scientific/Engineering :: Artificial Intelligence',
    ],
)

Then in the directory of the cloned repository, open a terminal and run python setup.py install to install the dependency.
