Convert IMU_RAW to ros message

[mdemirst]

Swift publishes raw imu and magnetometer messages. Can you convert them to ros imu message?

Hi, we decided to publish raw messages as are given by Piksi Multi, especially because there's a scaling factor you should consider when converting raw measurements to SI units for standard ROS message. You can covert them in standard ROS message using a custom python script for instance.
