We need to upgrade succbone to become a "full" harness for running repeatable experiments on vacuum quality.

Requirements

Output to control the roughing pump
2x output to simulate button presses
2x output to simulate two levels of the broken pirani gauge
No additional inputs needed, unless we want to monitor additional status from the evac controller

so in total >= 5x relay output.

~@llb~ @q3k and I briefly discussed to also have the succbone read, log and act upon temperature probes attached to the diffusion pump. Not the binary >= 60° the SEM is relying on, but rather some somewhat accurate (or at least stable) temperature sensors (K-Type? TMP101?) that would tell us

diffusion pump has turned on (> 40°)
diffusion pump is in a safe zone (< 200°?)
diffusion pump is in normal operating zone (oil-boiling-point-equivalent-if-measured-on-the-outside < x << oil-flash-point-equivalent-if-measured-on-the-outside)
diffusion pump is outside normal operating zone (> oil-flash-point-measured-on-the-outside)
GET OUT NOW LEAVE CHILDREN BEHIND (> oil flash point, but actually measured on the outside)

It might then, for example, also e-stop the diffusion pump or at least emit a very clear signal that someone should do that.
