Inertial Measurement Unit (IMU) classes and functions

These classes and functions provide support for optional IMU chips that may be present in some of the optional JeVois imaging sensors. For example, TDK InvenSense ICM20948: 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, integrated digital motion processor (DMP).
