NordicDfuProtocol

Nordic Semiconductor Secure DFU v2 protocol implementation.

Transfers firmware in two phases: first the init packet (command object), then the firmware binary split into data objects whose size is negotiated with the peripheral. Each object is CRC32-verified before execution. Supports partial resume — if the peripheral already has a valid prefix of an object, only the remaining bytes are sent.

This is the default DfuProtocol used by DfuController.
