ROS 2 one-liner install update

[horverno]

Thanks, for this awesome work. For convenience, i updated the one-liner install at the readme. Basically in ROS 2 the steps are the following:

cd ~/ros2_ws/src/

git clone https://github.com/PRBonn/kiss-icp

cd ~/ros2_ws/

colcon build --packages-select kiss_icp

Which can be merged into one line:

cd ~/ros2_ws/src/ && git clone https://github.com/PRBonn/kiss-icp && cd ~/ros2_ws/ && colcon build --packages-select kiss_icp

After source it can be started with e.g:

ros2 launch kiss_icp odometry.launch.py topic:=/lexus3/os_left/points
