Add a named default value for the height units

[TheRealAvise]

As always thank you for the great device and continued work on the software part of it.

Would it be possible to add a named default value for the height units in the config.yaml, as it is done for the desk variant or the min/max height? Right now it is hard-coded to default to in.

This would allow for an easy substitution in ESPHome with whatever is considered the real default, in my case cm.

Sure, that shouldn't be too difficult. I'll add it in the next release
