hmelder 6f93b96c39 succd: do not early return on error in modbusUpdate 
When one device fails, this should not influence updates of the other
devices.  Thus, early return was the wrong strategy here.

Instead, when communication with a device fails, skip the process data
update and continue with the next device.

hmelder d8a467a0c4 succd: Split scope lock into multiple blocks
All checks were successful

/ test (pull_request) Successful in 10s
Details 
We noticed huge load spikes with the latest changes.  This was caused
by the modbus goroutine blocking the entire daemon for long periods of
time while doing its data transfer.

Fix this by only holding the lock while performing data accesses.

Highlight out-of-range temperatures for the user.  The limits are
currently by intuition and should be reconsidered.

Rahix 52231a9e9c succbone: Add new mount
All checks were successful
/ test (push) Successful in 10s
Details 
This mount is a new iteration with the following improvements:

- 25% less DIN rail space required.  This allows installing 25% more
  Modbus-based technology!
- Designed for a clip that can be unlatched more easily.
- Fixed the BeagleBone hole pattern to match reality (why BeagleBone,
  why D:)

For more detailed monitoring, let's export all process values that are
exposed to the web API as prometheus metrics.

Rahix bd40c4f8df succd: Update rough vacuum hysteresis once more

/ test (push) Successful in 10s

We see fluctuation slightly above 4e-2 mbar so let's increase the
hysteresis value a bit more.

Rahix 637f8748a8 succd: Only show voltage on hover
All checks were successful
/ test (push) Successful in 10s
Details 
Another HP HMI thing: "Only show information that is immediately
relevant".  Let's hide the pirani voltage as it is mostly no longer
interesting to the user.  For situations where it is, it can be revealed
by hovering over the pirani pressure value.

Rahix 1e21222705 succd: Optimize color usage for HP HMI 
In the process automation world, there is a trend to move away from
colorful user-interfaces, towards more "boring" colorschemes.  The
argument is about situational awareness - by only using colors to
highlight abnormal situations, they become instantly recognizable to the
operators.

This design philosophy is outlined by the ISA-101 [1] under the name
"High Performance HMI".  While it covers much more than just colors, I
think this is the most important part and the one that is most
applicable for our usecase.

So let's do a bit of HP HMI - reduce colors usage such that only
important information is highlighted.

It seems we can get away with less hysteresis still.  Make the values a
bit smaller.

Rahix 8645718748 succd: Add hysteresis feature to thresholdOutput blocks 
Add a hysteresis value that can be optionally configured for

outputs from feedback that is caused by the thresholdOutput itself.
