Add support for ROS2 version of branch: point-lio-with-grid-map

[LihanChen2004]

Completed testing in Ubuntu22.04 + ROS2 Humble.

Simulated and real-world environments both showcase excellent performance odometry using mid360!

Compared to the master branch, the most significant improvement I've noticed is that there's no longer a half-minute delay in the simulation environment.
