added lorawan example in IAR, and added support for LIS3MDL and LPS22HB sensors

1. modified the HTS221: removed magic numbers, added a sensor_tempnhumi_t struct to accommodate temperature and humidity data 2. added .h and .c files for LIS3MDL magnetic sensor 3. added .h and .c files for LPS22HB pressure sensor 3. added IAR (EWARM) project for lorawan example 4. added bsp.c and bsp.h to manager the sensors

+  * @brief      This file contains basic functions prototypes and pre-definitions 
+  *             of the register addresses
+  ******************************************************************************
+  * @attention
+  *
+  * 1. the temperature sensor embedded in the LIS3MDL is intended to be embedded 
+  *    temperature compensation. Therefore, in this file we DO NOT include the
+  *    temperature output
+  *
+  * 2. on the P-NUCLEO-LRWAN3, the SDO/SA0 pad is connected to voltage supply(
+  *    via a resistor), LSb is <20><>1<EFBFBD><31> (address 1011101b)
+  *
+  * 3. for more information, please refer to the datasheet
+  *    (https://www.st.com/resource/en/datasheet/lis3mdl.pdf)
