Add new device type mappings, add note about 'used_for_public' (#713)

* add 'used_for_public' getter and setter

Not entirely sure what this command does, but I think it has to do with enabeling/disabeling developer mode.
In any case, I came accross this command while sniffing gateway trafic

* move used_for_public to comments

* remove space

* add 2 devices and the zigbee_ids as comments

* add values to used_for_public

* add zigbee_id

* fix black formatting
