pyzmq missing from requirements.txt while import zmq is unconditional

[GaneshPatil7517]

• File: requirements.txt + concore.py line 6
• concore.py does import zmq at the top level, but pyzmq is NOT listed in requirements.txt. Fresh pip install -r requirements.txt will crash with ModuleNotFoundError.
• Fix you can PR: Add pyzmq to requirements.txt

Thanks, @GaneshPatil7517 for your fix. But @avinxshKD has already fixed this in the dev. Please test and develop against the dev branch. Main branch is frozen for frequent fixes. We merge the dev branch eventually and periodically into the main branch.
