Zeppelin Air: reconstructing USB firmware recovery

Zeppelin Air Recovery reconstructs the Bowers & Wilkins speaker's USB recovery procedure from its updater library and live DFU exchanges. A Python tool implements vendor commands, flashes the MCU and coprocessor in two phases, and polls the coprocessor until it is ready; protocol notes document the message sequence and flash layout.
