[H3LIS331DL] Driver for the H3LIS331DL High-G accelerometer

Features and excluded features

Implementation of the H3LIS331DL driver. The driver supports:

• Reading 3-axis data.
• Setting the Output Data Rate of the sensor (beware that the ODR also sets PowerMode).
• Setting the Block Data Update.
• Setting the Full Scale Range of the sensor, thus the sensitivity.
• Setting the PowerMode to low consumption/normal mode by setting ODR lower than/greater or equal to 50 Hz.

Features that were left out:

• Interrupt 1 and 2, as both interrupts act like triggers that activate after a certain (customizable) threshold of acceleration is reached and they find no use in the application of the final product.
• High Pass Filter as it founds no use in the final product.

Just some final notes.

• The sensor is very noisy at high ODR.
• The three axis are also offsetted by certain amounts that change based on the Full Scale Range ( see #103 (closed) ).
