fix pid

1. Migrate from microDS18B20 to DallasTemperature
2. Refactoring of sensors: added an external temperature sensor inside the house, added an "offset" parameter for sensors
3. Fixed PID
4. New parameters added:
- settings.heating.minTemp
- settings.heating.maxTemp
- settings.dhw.minTemp
- settings.dhw.maxTemp
- settings.pid.minTemp
- settings.pid.maxTemp
- settings.sensors.outdoor.type
- settings.sensors.outdoor.pin
- settings.sensors.outdoor.offset
- settings.sensors.indoor.type
- settings.sensors.indoor.pin
- settings.sensors.indoor.offset
5. Fixed and updated HomeAssistantHelper
7. Added check for validity of settings. After some updates, the settings may be reset to default, but this will prevent the settings from being distorted.

 #### Instructions for fit coefficients:
 **Tip.** I created a [table in Excel](/assets/equitherm_calc.xlsx) in which you can enter temperature parameters inside and outside the house and select coefficients. On the graph you can see the temperature that the boiler will set.
 
-1. The first thing you need to do is to fit the curve (***N*** coefficient). If your home has low heat loss, then start with 0.5. Otherwise start at 0.7. When the temperature inside the house stops changing, increase or decrease the coefficient value in increments of 0.1 to select the optimal curve.<br>
+1. Set the ***K*** and ***T*** coefficients to 0.
+2. The first thing you need to do is to fit the curve (***N*** coefficient). If your home has low heat loss, then start with 0.5. Otherwise start at 0.7. When the temperature inside the house stops changing, increase or decrease the coefficient value in increments of 0.1 to select the optimal curve.<br>
 Please note that passive heating (sun) will affect the house temperature during curve fitting. This process is not fast and will take you 1-2 days.
-Important. During curve fitting, the temperature must be kept stable as the outside temperature changes. The temperature does not have to be equal to the set one.<br>
-For example. You fit curve 0.67; set temperature 23; the temperature in the house is 20 degrees while the outside temperature is -10 degrees and -5 degrees. This is good.
-2. After fitting the curve, you must select the ***K*** coefficient. It influences the boiler temperature correction to maintain the set temperature.
-For example. Set temperature: 23 degrees; temperature in the house: 20 degrees. Try setting it to 5 and see how the temperature in the house changes after stabilization. Select the value so that the temperature in the house is close to the set.
-3. Now you can choose the ***T*** coefficient. Simply put, it affects the sharpness of the temperature change. If you want fast heating, then set a high value (6-10), but then the room may overheat. If you want smooth heating, set 1-5. Choose the optimal value for yourself.
+Important. During curve fitting, the temperature must be kept stable as the outside temperature changes.<br>
