TPMS sensors - cache last values to report even when car is off

[jgoldman1]

TPMS sensors report "unknown" when car is not in use. Would be helpful to cache most recent values and keep them persistent while car is off.

This may not be as big of an issue. My car is now reporting TPMS sensor data, even when car is off. Looks like it needed one power-up and drive after installing the lucid integration before it starts working. So really not a big deal.

Lucid caches the value on their end for maybe 15-30 minutes after driving, but then it goes back to unknown. We may still want to cache the last known value.
