v1.2.12

• Pull-requst (@medlor #92):
  Added #ifndef/#define in config.h
  New funtions: dataWaitingAsync() and updateAsync()
  +some other minor changes
• Issue(@foofel #87): fix variables in HX711_ADC.h (e.g. startStatus) not initialized to 0

v1.2.11

• Renamed new function setReverseVal() to more intuitive setReverseOutput().

v1.2.10

• Added function setReverseVal(). If you get a negative output value that should be positive, you can use this function rather than re-solder the loadcell wires. Tare/Zero-offset must be set after calling setReverseVal(), so it's best to call this function after begin() as shown in the example files.
