the bit move of signed values automatically extend sign the mask and sign extension was buggy in Adafruit_MAX31855::readCelsius, because v = 0xFFFFC000 | ((v >> 18) & 0x00003FFFF); has to be v = 0xFFFFC000 | ((v >> 18) & 0x00003FFF); the value is only 14 bits and not 18!

the bit shift of signed values automatically extend sign
the mask and sign extension was buggy in Adafruit_MAX31855::readCelsius, because
v = 0xFFFFC000 | ((v >> 18) & 0x00003FFFF);
has to be
v = 0xFFFFC000 | ((v >> 18) & 0x00003FFF);
the value is only 14 bits and not 18!
