L3GD20: Enable L3GD20 3-axis digital gyroscope library and example

L3GD20 is tri-axis gyroscope from STMicroelectronics.
This sensor can measure angular velocity in degree per second.

The library provided is libupm-l3gd20.so.0.4.0.
The example provided is l3gd20-example where it will print x,y,z axis when
trigger buffer data is ready.

This sensor requires calibration to be done for 2 seconds. Please place the
sensor on level surface.

As the sensor data is noisy, we have implemented denoise algorithm within the
sensor library.
