[hdpowerview] Hunter Douglas PowerView Binding - Auto-discovery of Existing Thing

• Version used: openHab 4.3.1
• Operating System and version: Windows 10

The binding works very well, but keeps auto-discovering my Hunter-Douglas PowerView Gen 2 Hub, even after ignoring it.

According to the following, https://www.openhab.org/docs/developer/bindings/thing-xml.html#representation-property, a representation property is used to auto-ignore discovery results of Things that already exist in the system. This can happen if, a) a Thing has been created manually, or b) the Thing has been discovered separately by two mechanisms e.g. by mDNS, and by NetBios, or UPnP. If this is the case, the Thing in the inbox is automatically ignored. Note that this Thing is automatically removed when the manually added Thing is removed. A new discovery would then automatically find this Thing again and add it to the inbox properly.

It would be great to add this feature.
