Fix no module named homeassistant.util.distance

[danielnolan]

• homeassistant.util.distance was deprecated in HA 2022.10 and this
  no module error is preventing me from setting up mila on 2023.11.0
• Use DistanceConverter.convert from homeassistant.util.unit_conversion
• Fixes distance_convert deprecated #18

This is what I was seeing before my change to use the new DistanceConverter

Thanks for the PR. Do you know if this will break the installs pre 2023.11.0?

[danielnolan]

I believe the old module was removed in version 2022.4, so any version between then and now should work with this update.

@kbromberger mind testing this again?

@sanghviharshit I can confirm these changes do fix the issue.
