SEN-14001 firmware stability and performance updates

Be sure to update to version V_1.0.2 of SparkFun_MPU-9250-DMP_Arduino_Library from https://github.com/lebarsfa/SparkFun_MPU-9250-DMP_Arduino_Library.

ROS-specific firmware updates

Known issues : nan might appear randomly after some time for the angles, as well as unexpected gyrometers and accelerometers values from time to time... Not sure why... Try to unplug, wait 5 min and try again, until a real solution is found... As a temporary potential workaround, try to get the magnetometers calibration values using this firmware and use that firmware with ROS : https://github.com/lebarsfa/9DOF_Razor_IMU (note that it will ignore the calibration values sent by ROS).
