Set debug level and stream

The IoT Agent library comes with its own debugging library.

The debug level can be set using the setDebugLevel method.

setDebugLevel(DebugLevel::DEBUG)

The default debug level is `WARN`

The debug levels are:

• `DebugLevel::OFF`

• `DebugLevel::ERROR`

• `DebugLevel::WARN`

• `DebugLevel::INFO`

• `DebugLevel::DEBUG`

• `DebugLevel::TRACE`
  
  

You can also set the stream in which the debug messages will be sent by using the setDebugStream method.

setDebugStream(&Serial)

The default debug stream is Serial.
