This package contains a node that translates motion capture data from an
    OptiTrack rig to tf transforms, poses and 2D poses. The node receives
    packets that are streamed by the Tracking Tools software, decodes them and
    broadcasts the poses of configured rigid bodies as tf transforms, poses,
    and/or 2D poses.
     
    Currently, this node supports the NatNet streaming protocol v2.2
