/*================== Thermal Runaway Protection ==============================
This is a feature to protect your printer from burn up in flames if it has
a thermistor coming off place (this happened to a friend of mine recently and
motivated me writing this feature).
The issue: If a thermistor come off, it will read a lower temperature than actual.
The system will turn the heater on forever, burning up the filament and anything
else around.
After the temperature reaches the target for the first time, this feature will
start measuring for how long the current temperature stays below the target
minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).
If it stays longer than _PERIOD, it means the thermistor temperature
cannot catch up with the target, so something *may be* wrong. Then, to be on the
safe side, the system will he halt.
Bear in mind the count down will just start AFTER the first time the
thermistor temperature is over the target, so you will have no problem if
your extruder heater takes 2 minutes to hit the target on heating.
