Some errors will never appear...

Hi,

as far as i see, the errors

MAX31865_FAULT_REFINLOW
MAX31865_FAULT_REFINHIGH
MAX31865_FAULT_RTDINLOW

will never appear.
These are the bits 3 to 5 in the fault register, which are only handled, if a fault-detection cycle is initiated through the config register. Neither readFault() nor any other method seems to trigger a fault-detection cycle.
Could be a great improvement to do this alway in readFault() or to overload the method and give a parameter to trigger automatic or manual fault-detection mode.
Currently an unconnected sensor could not be detected through readFault(), but this is implied trough the example.

Edit:
I supplied two patches for the .cpp and .h files with an extended readFault() method. Just call readFault(true) to initiate a fault-detection cycle. readFault(false) gives the same result as readFault().
To be improved... :-)
