safe queue size for netft_node.

[chaitanyantr]

Query:- May I know what should be the safe range for queue size in ros2 publisher? considering the sensor rate is 500hz (claimed).
Reason:- continuous message loss issue.
Image:-

// Set up ROS publishers
auto node = std::make_sharedrclcpp::Node("netft_node" + last_digit);
const rclcpp::QoS qos(100);
rclcpp::Publisher<std_msgs::msg::Bool>::SharedPtr ready_pub = node->create_publisher<std_msgs::msg::Bool>("netft_ready" + last_digit, qos);
rclcpp::Publisher<geometry_msgs::msg::WrenchStamped>::SharedPtr geo_pub = node->create_publisher<geometry_msgs::msg::WrenchStamped>("netft_data" + last_digit, 500);
