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
