static_transform_publisher in launch is causing TF conflicts. Could you make it OPTIONAL?

Hello developers,

I would like to request that this part of the launch file to be OPTIONAL.
It is good for testing the ydlidar out-of-the-box.
But, it is causing conflicts if e.g. we already have our own robot_descriptions that publishes our own
TF base_link->laser_frame.

Since a CHILD FRAME is not allowed to have multiple PARENT FRAME, the static tf publisher in current launch file is causing either one TF link to be removed or ignored.
