Adding a new world: Aruco checkerboard

[Witty-Wizard]

I want to add a new world with the checker board for pose estimation of aruco codes. I have cloned the repository and when I run the launcher script the simulation launches successfully, but when I change the world file and then run the simulation the changes are not reflected, as I understand I am doing something wrong, can someone guide me how to do this properly

Can you share your world file? One thing to note is we recently moved to using a server config file

I tried replacing aruco image with the following image. I edited the existing file to add this image
