[PyQt] ANN: PyQt v5.9.1 and SIP v4.19.4 Released

[Phil Thompson]

PyQt v5.9.1 has been released (along with corresponsing releases of PyQt3D, PyQtChart, PyQtDataVisualization and PyQtPurchasing). These add support for Qt v5.9.2.

The Linux wheel for PyQt has yet to be uploaded to PyPI as it seems to have hit a limit on the size of a wheel. I'm trying to get this resolved.

SIP v4.19.4 has also been released. This includes the ability to add enable (at runtime) strict overflow checking when converting from Python integers.
