Using Constraint Time Uncertainty(C-TUNC) APIs

Please follow below steps to enable/disable C-TUNC

### 1. Implement a command response function ###

void CmdResponse(ErrorCode error) {
    if (error == ErrorCode::SUCCESS) {
        std::cout << " Command executed successfully" << std::endl;
    }
    else {
        std::cout << " Command failed\n errorCode: " << static_cast<int>(error) << std::endl;
    }
}

### 2. Get the LocationFactory instance ###

auto &locationFactory = LocationFactory::getInstance();

### 3. Get LocationConfigurator instance ###

auto locConfigurator_ = locationFactory.getLocationConfigurator();

### 4. Wait for the Location Config. initialization ###

bool subSystemStatus = locConfigurator_->isSubsystemReady();
if (!subSystemStatus) {
    std::cout << "Location Config. is not ready, Please wait!!!... "<< std::endl;
    std::future<bool> f = locConfigurator_->onSubsystemReady();
    subSystemStatus = f.get();
}

### 5. Exit the application, if SDK is unable to initialize Location Config. ###

if (subSystemStatus) {
    std::cout<< "Location Config. is ready" << std::endl;
} else {
    std::cout << " *** ERROR - Unable to initialize Location Config."<< std::endl;
    return -1;
}

### 6. Enable/Disable Constraint Tunc API ###

locConfigurator_->configureCTunc(enable, CmdResponse, optThreshold, optPower);

7. Command response callback is invoked with error code indicating SUCCESS or FAILURE of the operation.
