option to use entity numbers instead of names

PAI sends MQTT messages into topics pattern like "paradox/states/zones/name/property". In case of changing the zone labels, it requires the reconfiguration of any systems receiving the messages.

Feature description

It would be useful to have a configuration option, when enabled the mqtt topics look like "paradox/states/zones/zone#/property" (and likewise for other entities as partitions, outputs, etc). Also the entity name could be published in a separate subtopic (e.g. paradox/states/zones/zone#/label")
