* Fix reversed door closing/opening states in HomeKit
When we closed the door we would set state 2 which
is "Opening" it should have been 3 which is
"Closing"
When we opened the door we would set state 3 which
is "Closing" it should have been 2 which is
"Opening"
Add constants to make this easier to catch
in the future.
* Remove debug
* Add note about target door state
