Add Thermal Limit Events to Thermal Manager

Add Thermal Limit Events to Thermal Manager

Description

Adds four events in Thermal Manager for when the face and battery temperature sensors read above or below a certain temperature. These thresholds are set with a parameter to the Thermal Manager.

These events can be used to log when the temperature is above or below a given temperature.

Further Notes / Considerations

@Mikefly123 How does this range look?

[Mikefly123]

This does look great to me! I will note though that on the Yearling satellites we consistently saw Face temperatures around -34C in eclipse, so I recommend throttling this event or adding some logic that will debounce it so we don't get too much spam.

At what temps did we start seeing issues with hairsat?

[Mikefly123]

Thanks for the reminder on that actually! I would recommend changing that battery low temp threshold to something much more conservative, like 5C. If Lithium Ion batteries go below 0C they can still discharge but can suffer long term damage if you charge them at freezing temperatures.

As for the face temperatures, we still can generally read stalely down to -40C. Below that you start running into issues!

Looks correct, waiting on @Mikefly123 for thoughts on default values.
