/**
* Configuration options for MAX Thermocouples (-2, -3, -5).
* FORCE_HW_SPI: Ignore SCK/MOSI/MISO pins and just use the CS pin & default SPI bus.
* MAX31865_WIRES: Set the number of wires for the probe connected to a MAX31865 board, 2-4. Default: 2
* MAX31865_50HZ: Enable 50Hz filter instead of the default 60Hz.
* MAX31865_USE_READ_ERROR_DETECTION: Detects random read errors from value spikes (a 20°C difference in less than 1sec)
* MAX31865_USE_AUTO_MODE: Faster and more frequent reads than 1-shot, but bias voltage always on, slightly affecting RTD temperature.
* MAX31865_MIN_SAMPLING_TIME_MSEC: in 1-shot mode, the minimum time between subsequent reads. This reduces the effect of bias voltage by leaving the sensor unpowered for longer intervals.
* MAX31865_WIRE_OHMS: In 2-wire configurations, manually set the wire resistance for more accurate readings
* Thermocouple Options for MAX6675 (-2), MAX31855 (-3), and MAX31865 (-5).
