python-css-parser fails to build with Python 3.13.0a1.

According to https://docs.python.org/3.13/whatsnew/3.13.html module cgi was
removed:

PEP 594: Remove the cgi and cgitb modules, deprecated in Python 3.11.

cgi.FieldStorage can typically be replaced with urllib.parse.parse_qsl() for
GET and HEAD requests, and the email.message module or multipart PyPI project
for POST and PUT.

cgi.parse() can be replaced by calling urllib.parse.parse_qs() directly on the
desired query string, except for multipart/form-data input, which can be
handled as described for cgi.parse_multipart().

cgi.parse_multipart() can be replaced with the functionality in the email
package (e.g. email.message.EmailMessage and email.message.Message) which
implements the same MIME RFCs, or with the multipart PyPI project.

cgi.parse_header() can be replaced with the functionality in the email package,
which implements the same MIME RFCs. For example, with
email.message.EmailMessage:

from email.message import EmailMessage
msg = EmailMessage()
msg['content-type'] = 'application/json; charset="utf8"'
main, params = msg.get_content_type(), msg['content-type'].params

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.13/fedora...

For all our attempts to build python-css-parser with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/pytho...

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package
builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all
pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive
[Build]Requires),
so if this package is required a lot, it's important for us to get it fixed
soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work
around it on our side.
