Twisted IOCP Support

twisted-iocpsupport provides a C extension for Twisted's I/O Completion Ports (IOCP) reactor, primarily used on Windows for high-performance asynchronous I/O. It enhances the `twisted.internet.iocpreactor` module, making the IOCP reactor available for use. The current version is 25.10.1, with releases typically tied to Twisted's release cycle and Python version support, focusing on platform compatibility and binary wheels.
