Many changes.

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.
