Remove unused sip dependency for Python 3.8 compatibility
Remove unused sip dependency for Python 3.8 compatibility

The sip module is not needed. We also remove the PyQt5-sip dependency
as PyQt5 already has a dependency on the correct version. This makes
Python 3.8 usable as PyQt5-sip Python 3.8 wheels are only built for
newer versions.
