Add support for Philips Hue Datura Small Round Ceiling Lamp

[WyspSedai]

The light fixture presents itself as two seperate entities/lights within one fixture. Listed both items, unsure of how or if able to combine them as one

The device is listed as supported in the database, however my version(?) pops up as unsupported in the Z2M add-on when joining the device to my network.
