react-native-compass-heading

native-seam: the start/stop NativeEventEmitter wrappers run from the bundle; the CompassHeading module backs them with the real DeviceOrientationEvent (webkitCompassHeading on iOS Safari, else the alpha angle converted to a clockwise compass heading — the same source expo-location.getHeadingAsync uses, kept consistent), emitting the HeadingUpdated { heading, accuracy } events upstream subscribes to, throttled by the caller’s update_rate degree threshold
