Implement Firmware Updates

[marcus-j-davies]

And so it begins

// Extract the firmware from a given firmware file
let actualFirmware: Firmware;
try {
    const format = guessFirmwareFileFormat(filename, rawData);
    actualFirmware = extractFirmware(rawData, format);
} catch (e) {
    // handle the error, then abort the update
}

// try the update
try {
    await this.driver.controller.nodes
        .get(nodeId)!
        .beginFirmwareUpdate(
            actualFirmware.data,
            actualFirmware.firmwareTarget,
        );
    console.log(`Node ${nodeId}: Firmware update started`);
} catch (e) {
    // handle error
}
