v4.6.0

Added

• A device is created in Home Assistant in the room of its channels. The
  discovery config carries the room as the device's suggested_area (task
  18). It did so before only when every channel of the device lay in one and
  the same room: a device with channels in two rooms got no area, and on
  openccu-lite, whose rooms can be nested and whose room list of a channel
  names the parents too (Küche, Erdgeschoss), no device got one at all.
  Now the area is the room shared by all channels of the device that lie in a
  room, otherwise the room of the lowest-numbered channel that lies in one; a
  channel in several rooms counts with its first (on openccu-lite the most
  specific), and a room of the device itself comes first. The rooms are the
  ReGaHSS's on a CCU and the system's metadata's on openccu-lite. New option
  Suggest the channel's room as the device's area on the node, on by
  default. Home Assistant applies the suggestion only when it first creates
  the device; a room changed later stays as assigned in Home Assistant.
