When a carrier provides an "anchor" of data usage at a specific moment in time, augment the network statistics used by warning/limit thresholds and Settings UI. For example, if the OS measured 500MB of usage, but the carrier says only 400MB has been used, we "squish" down the OS measured usage to match that anchor. Callers using the hidden API will have their data augmented by default, and the public API offers a way to opt-into augmentation. Thorough testing to verify behavior.
