New driver for the IMU devices from XSens

The ASL is happy to announce a new driver for the IMU devices from XSens. This driver is a small python implementation of most of the MT protocol and supports both serial and USB interfaces for MTx, MTi and MTi-G devices. It is split between a Python module with a command line interface to configure the device, and a ROS node that publishes the information streamed by the IMU on standard topics (mainly /imu/data and /fix for the MTi-G).

The driver is available in the ethzasl_xsens_driver stack.
