+Based on the excellent `QuinLED_Dig_Uno_Temp_MQTT` by srg74 and 400killer!  
 This usermod will read from an attached DS18B20 temperature sensor (as available on the QuinLED Dig-Uno)  
 The temperature is displayed both in the Info section of the web UI as well as published to the `/temperature` MQTT topic if enabled.  
 This usermod will be expanded with support for different sensor types in the future.
