fnb58-ble-logger: FNB58 Bluetooth measurement protocol

fnb58-ble-logger reconstructs the FNIRSI FNB58's Bluetooth LE measurement exchange and logs voltage, current and power to daily CSV files. Its Linux daemon writes the stream-start commands, reassembles notification frames and decodes type 04 measurements; the repository documents the observed GATT layout and frame format.
