Implement temp history to model

[EnUfor]

Temp sensors are hard to sense if disconnected, except if SCL or SCA is disconnected at startup. Relying on temperature randomness and checking if the readings are outside set bounds is my best bet at ensuring the sensors are still reading good.

Implement a circular buffer (hopefully within the model) to track temperature changes over time. Run some sort of analysis to see if values are too flat. Might also need to track fan speed changes over time to get an appropriate response.
