====================================================

This module provides Adafruit defined advertisements.

Adafruit manufacturing data is key encoded like advertisement data and the Apple manufacturing data.
However, the keys are 16-bits to enable many different uses. Keys above 0xf000 can be used by
Adafruit customers for their own data.
