Arduino library to support the LIS3MDL high-performance 3-axis magnetometer.

• LIS3MDLSensor(TwoWire*, uint8_t): class constructor
  Params pointer to the I2C instance
  Params (optional) address of the component's instance

• Enable: enable sensor
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• Disable: disable sensor
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• ReadID(uint8_t*): read ID address
  Params pointer where store the ID of the device
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• GetAxes(int32_t*): read magnetometer data
  Params pointer where to store data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• GetSensitivity(float*): read magnetometer sensitivity
  Params pointer where to store data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• GetAxesRaw(int16_t*): read magnetometer raw data
  Params pointer where to store data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• GetODR(float*): get the output data rate mode
  Params pointer where to store data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• SetODR(float): set the output data rate mode
  Params data rate to be set
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• GetFS(float*): get the magnetometer full scale
  Params pointer where to store data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• SetFS(float): set the magnetometer full scale
  Params full scale to be set
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• ReadReg(uint8_t, uint8_t*): read data from register
  Params register address
  Params pointer to register data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• WriteReg(uint8_t, uint8_t): write data to register
  Params register address
  Params register data
  Returns LIS3MDL_STATUS_OK in case of success, an error code otherwise

• DISCO_IOT_LIS3MDL_DataLog_Terminal: reads magnetometer axes values and prints them.
