Extend measuring range of thermocouple for MAX31855

It extend measuring range of thermocouple from 1023℃(upper limit of MAX6675 - 1℃) to 1799℃(upper limit of MAX31855 - 1℃),
and from 0.01℃(lower limit of MAX6675 + 0.01℃) to -269.99℃(lower limit of MAX31855 + 0.01℃).

In case of 3D printing with melted iron, over 1500℃ is needed.

...And In case of 3D printing with ice cream, maybe under 0℃ is needed...

#elif TEMP_SENSOR_0 == -2
#define HEATER_0_USES_MAX6675
#define MAX6675_TMIN 0
#define MAX6675_TMAX 1024

Is it better that these are written in temperature.h?
