how to run kitti dataset in EKF_LOAM

[mengtangxin]

Hi, I want to use kitti dataset using EKF_LOAM, but there are some errors occurring.

1. After modifying the configuration file according to LEGO_LOAM to run, the following issues occurred: [ INFO] [1693649227.318221864, 1317617735.043216158]: Waiting for Transformation
   [PreTreatment-6] process has died [pid 24086, exit code -11, cmd ///ekf_loam/devel/lib/ekf_loam/PreTreatment __name:=PreTreatment __log:=///.ros/log/6fd32b58-4978-11ee-8b00-08beac2670b6/PreTreatment-6.log].
2. After inspection, it was found that there were no TF nodes.
   I would like to know if there are any other modifications needed besides modifying the parameter configuration file of the LiDAR. Thanks a lot!
