Using SENSOR_DELAY_UI

[niqo01]

Reading at the documentation SENSOR_DELAY_UI seams more appropriate instead of SensorManager.SENSOR_DELAY_FASTEST

During initial development of the library, I looked into using a slower sensor delay. A slower rate would certainly be preferred because of battery concerns. Unfortunately I found that SensorManager.SENSOR_DELAY_FASTEST is the only sampling period that allows the parallax effect to exist without significant jank and maintain a steady 60 fps frame rate.

@nvanbenschoten would it be possible to add the possibility to the library users to tweak this value according to their need?

If you want to throw together a pull request that gives ParallaxImageView.registerSensorManager() an optional sensor delay parameter with a default delay of SensorManager.SENSOR_DELAY_FASTEST, I wouldn't see a problem with that.
