v1.2.0

• New function: refreshDataSet()
  fills the dataset up with new conversions (this function is blocking once started)

• New function: getDataSetStatus()
  returns 'true' when the whole dataset has been filled up with conversions after a reset/restart

• New function: getNewCalibration(float known_mass)
  returns and sets a new calibration value (calFactor) based on a known mass input

• New function: getSignalTimeoutFlag()
  returns 'true' if it takes longer time then 'SIGNAL_TIMEOUT' for the dout pin to go low after a new conversion is started

• New function: start(unsigned int t, bool dotare)
  start with or without tare

• New function: startMultiple(unsigned int t, bool dotare)
  start with or without tare

• Calibration example sketch improvements:
  Tare offset is now initiated as a seperate step before you place the known mass
  New function getNewCalibration(float known_mass) implemented
  New function refreshDataSet() implemented
  A simplified description of the calibration procedure now included on top

• Interrupt example sketch improvements:
  Some changes in ISR and loop()

• All example sketches:

  • Method for calling functions 'getData()' and 'update()' changed:
    Set variable 'serialPrintInterval' to '0' to print any new data imidiately, or set a higher value to slow down the terminal print activity
  • EEPROM ESP specifics changed from #if defined(ESP8266) to #if defined(ESP8266) || defined(ESP32)
  • I/O pins declared before constructor, HX711_dout/HX711_sck
  • Serial bitrate changed to 57600
  • There are also some other minor changes and cleaning, to clarefy things mostly
