Fix proliphix (#34397)

* Retrieve the name of the Proliphix thermostat before adding the entities

* The proliphix module provides hvac_state, not hvac_mode

* Removed update before add_entities. Moved the setting of the name into the update function instead.

* Disentangled hvac_mode and hvac_action

* Ran black and isort
