Request to Declare Python 3.13 Compatibility on PyPI

[grokas-splunk]

Hey requests-ntlm maintainers,

I am reaching out on behalf of Splunk SOAR, as part of our internal migration effort to Python 3.13.

What we’re requesting

• Confirm whether this package is compatible with Python 3.13
  • I was able to run the package tests in a 3.13 environment, getting them passing successfully
• Update the package metadata to reflect Python 3.13 compatibility for easier tracking and recognition, and publish a new PyPI release

Thanks a ton for your support in this matter.

Best, Splunk SOAR Engineering Team
