Control P1S chamber fan with Temp input

[steve3j]

Feature Description

Ability to power up/down chamber fan based on the temperature input from temp sensor.

Justification

"Chamber fan is controller by gcode depending on the temperature of the bed, there is no direct link between chamber temp and fan speed."

There's no real automated control of the chamber temp currently.
Having the ability to turn on the heated bed, then set the chamber temp based on a desired value would be beneficial because it would give more consistent print results. I keep having my first print not stick to the bed very well, but if I let the chamber warm up first(or print the exact same thing after the first one fails), it sticks fine.

Suggested Implementation (if you have one)

PID loop to turn down fan if desired temp is not reached, turn up fan if temp is reached.
Or simple histeresis, turn on at desired temp, turn off 2 deg below desired value.

This could be very helpful in more reliable prints as well as noise reduction.
