setting QSensors data rate for Android has no effect

Setting the data rate of a sensor has no effect for Android.

According to this: https://developer.android.com/reference/android/hardware/SensorManager.html#registerListener(android.hardware.SensorEventListener,%20android.hardware.Sensor,%20int,%20int)

Android expects the data rate to be in microseconds.

I believe the reason for this bug is that QtSensors expects dataRate to be in Hz, and there is no conversion between the two.

So, setting the dataRate of 2 Hz (2 times a second), actually sets the android sensor to 2 microseconds, where as it should be set to 500000 microseconds.

This is probably a long standing bug that no one has reported.
