update for ROS noetic and LIvox Mid 360

[slamer2024]

Thanks authors for sharing the awesome code. I edit some part of the code. I can run on the ROS noetic and Livox Mid 360. If you are interested, you can try. I also edit the readme. The versions for numpy and open3d are important. 宝子们，最近我在弄mid360。 把代码改了一丢丢。 如果你也遇到ros版本等问题，可以试试我的，我gazebo测试过，可以跑。 https://github.com/slamer2024/FAST_LIO_LOCALIZATION/tree/main
