Fix a few issues with CoreTemperature and add HSI

[rasher]

Found and fixed a few issues with CoreTemperature:

• The sensor wasn't included in the device lists, meaning it didn't show up in the command line tool options at least - possibly other issues as well
• Added support for Heat Strain Index value which was added somewhat recently (https://github.com/CoreBodyTemp/CoreBodyTemp/blob/main/CORE%20Connectivity%20Implementation%20Notes.pdf)
• Set data value to None upon receiving invalid values according to spec
• Fixed a typo CoteTemperatureData -> CoreTemperatureData
• Storing/updating event-count correctly, although it's not used for anything

I'm not 100% sure about the handling of invalid values. Setting it to None seems appropriate to me, but I'm not sure if it might have any unintended consequences down the line?

Failed check must be unrelated, a re-run from someone with permissions should fix it.

Yes undecided here too. Technically None isn't nice since the types aren't Optional[float] anyone using type checking is going to get a warning (not related to this PR but quality should actually default to CoreTempDataQuality.Unused). Perhaps propagating the profile invalid value itself without scaling: 0xFF, 0x800, etc? Someone using the Core Temperature device should know this is an invalid value from the sensor profile.

They should also initialise to either of these values too, rather than 0.0.

Yeah I think that makes sense. I've made constants of them so users can use those. Although that means they should be floats in order for the typing to work out, which feels a bit off.

I tense up when floats come up, should work out though since they're actually integers.

>>> float(0x8000) == 0x8000
True
>>> float(0x800) == 0x800
True
>>> float(0xFF) == 0xFF
True

It's a little wonky looking - I'm not sure if there's a more elegant solution short of doing a bunch of explicit conversions.

Looks good. Thanks.
