[How to] UART read without custom component

The UART Bus component provides a write action but no read actions. Typically the UART read is implemented in a custom component that also does the processing. The UART debug sequence can be exploited to act like a call back function whenever there is received data to process. So basically instead of creating a small custom component a large lambda call can be used in the UART debug yaml. This is shared to hopefully help make implementing UART devices a bit easier for average users. It seems t…

    - lambda: |-
          UARTDebug::log_string(direction, bytes);  //Still log the data
          
          int sensorID=0;
          float sensorTEMP=0; 
          
          //Example to convert uart text to string
          std::string str(bytes.begin(), bytes.end());

          //watch for potential problems with non printable or special characters in string
          id(rawString).publish_state(str.c_str());
