Support for QThread and QEventLoop added. This will enable ib_async to run in a separate worker.

[Flippo24]

I use ib_async in a separate QThread with its own QEventLoop. I had to adapt useQt for this. A custom QApplication context can now also be used.

Minimal example QApplication:

class Application(QApplication):
    def __init__(self, argv):
        super().__init__(argv)
        ...

util.patchAsyncio()
app = Application(sys.argv)
util.useQt('PySide6', qtContext=app)

in a worker thread i use:

util.patchAsyncio()
util.useQt('PySide6', qtContext=QThread.currentThread())
self.ib = IB()
self.ib.run()
