• New API function for multi-point linear regression calibration of pH and Orp sensors
• /!\ Former API function for the Offset Calibration of the pH and Orp sensors are no longer available
• getMeasures() function now based on calibrated linear function to compute pH and Orp values
• PublishDataCallback() function now using ArduinoJSON library to generate payload
• Eeprom, Webserver and XML file now store/display the calibration coefficients for the pH and Orp sensors
