[force_torque_sensor_broadcaster] wrench_transformer_node handles target frames as positional arguments

[Juliaj]

• It could be interesting to have a node like tf2_echo, so it would look like something like following

ros2 run force_torque_sensor_broadcaster wrench_transformer_node frame1 frame2 --ros-args -r __ns:=fts -r input:=wrench

Indeed @Juliaj, I also think it could be quite interesting to have a node like tf2_echo.

Whadya say, about its current implementation?
