Update import of hass temperature utilities

[mpkogli]

Version of the custom_component

Latest, v2.0.6

Configuration

- platform: optimal_humidity
  sensors:
    test_optimal_humidity:
      name: "Optimal Humidity"
      type: optimal_humidity
      indoor_temp_sensor: sensor.inkbird_temperature
      indoor_humidity_sensor: sensor.inkbird_humidity
      critical_temp_sensor: sensor.ibs_th_0888_temperature

Describe the bug

In the latest release, I'm getting the below error message in the logs. Looks like HASS moved the temperature conversion functions to a different module. PR created: #214

Thanks for the contribution @mpkogli ! Running it through now.

@mpkogli I'll need to rebase/reword the comment to fit the PR title I just posted. I use Conventional Commits to automate version bumps, releases, and release notes.

I'll look into that convention, thank you.

Hoping I can keep our whole home humidifier from causing condensation. Great project!

@mpkogli It has been pretty good in my home thus far; wild swings are hard to keep on top of, but a combination of dehumidification and ventilation does keep it to a minimum!
