feat: Nevermore Controller support

[pedrolamas]

Adds full support for Nevermore Controller.

Replaces #1114

This will break VOC plotting on the temp graph.

This is just extra sensor data (does not include temperature, just pressure, humidity and gas)

[SanaaHamel]

Note that there can be both nevermore <named> and nevermore objects, depending on how they are declared in the cfg.

Yes, I made sure to handle both as shown on the screenshot

@SanaaHamel This is the test objects state I am using (and how I generated the screenshot bove):

{
  "nevermore": {
    "rpm": 10,
    "speed": 20,
    "intake_temperature": 20,
    "exhaust_temperature": 30,
    "intake_humidity": 40,
    "exhaust_humidity": 50,
    "intake_pressure": 60,
    "exhaust_pressure": 70,
    "intake_gas": 80,
    "exhaust_gas": 90
  },
  "nevermore test": {
    "rpm": 10,
    "speed": 20,
    "intake_temperature": 20,
    "exhaust_temperature": 30,
    "intake_humidity": 40,
    "exhaust_humidity": 50,
    "intake_pressure": 60,
    "exhaust_pressure": 70,
    "intake_gas": 80,
    "exhaust_gas": 90
  }
}

However, I was looking at the controller code and noticed a _min and _max for each entity (like intake_temperature_min, intake_temperature_max, ...), are those also reported as part of the Klipper status object?

Also, am I correct ti say "pressure" and "gas" are fully int values (have no decimals)?

They are. These were requested by Mainsail for future use. These indicated the upper/lower bound seen this klipper session.

gas is an integer, pressure is a float (recommend rounding for display) though it is pre-rounded in NevermoreSensor for historical reasons.

I've added support for them, they will show as tooltips for the gas, temperature, humidity, and pressure.

Looks sane. Passed smoke test w/ my production unit.

Thanks for testing and approving, @SanaaHamel! 🙂
