Export lobally optimized occupancy grid map

[rdds]

Hello!

Currently I am using rtabmap-export to generate the poses.txt and cloud of a scanned environment. I would like to know if I could also export the occupancy grid without using the ros map_saver node. I know I can also generate the map using the rtabmap database viewer, but I want to generate all the 4 files (poses, cloud, occupancy grid pgm and yaml) together using a single command and the same optimization of the map trajectories.
