Multi instance uorb-ros2 topic transfering

[zhikh1]

I have 3 imu on my PX4 and want to get all 3 instance of sensor_gyro, sensor_accel topics. I have not yet found information on how this can be done in the current version. Please tell me how it is possible to do this if it is already available for use.
It is very important to support the multi instance topic translation mechanism.

We'll need to add a mechanism to handle this.
