Add node to publish the transform between UTM and map coordinates

Added a new node, scripts/utm_transform_publisher, that listens for
adjacent pairs of messages of the robot global and local position from
mavros and publishes the corresponding TF2 transform between UTM
coordinates and ROS map coordinates.
