Adding LSM6DSO32 arduino library source files

Summary

This Pull Request add the Arduino library source files to support the LSM6DSO32 3D accelerometer & 3D gyroscope.
It's based on the LSM6DSO library and provide the same interface.

Validation

Several examples are provided with the LSM6DSO32 library and have all been tested.

• LSM6DSO32_HelloWorld: This application provides a simple example of usage of the LSM6DSO32
  IMU 6-axis. It shows how to display on a hyperterminal the values of the sensor.
• LSM6DSO32_6DOrientation: This application shows how to use the LSM6DSO32 accelerometer
  to find out the 6D orientation and display data on a hyperterminal.
• LSM6DSO32_FreeFallDetection: This application shows how to detect the free fall event using the
  LSM6DSO32 accelerometer.
• LSM6DSO32_Pedometer: This application shows how to use the LSM6DSO32 accelerometer
  to count steps.
• LSM6DSO32_SingleTap: This application shows how to detect the single tap event using the
  LSM6DSO32 accelerometer.
• LSM6DSO32_DoubleTap: This application shows how to detect the double tap event using the
  LSM6DSO32 accelerometer.
• LSM6DSO32_TiltDetection: This application shows how to detect the tilt event using the
  LSM6DSO32 accelerometer.
• LSM6DSO32_WakeUpDetection: This application shows how to detect the wake-up event using the
  LSM6DSO32 accelerometer.
