Add config option for "expire_after"

[Cupmar]

On Homeassistant the following payload is received for the battery: I would like that the sensors in homeassistant are longer available before their values are discarded: Can "expire_after" be added to the config?

name: Elastica1 Battery unique_id: c47c8d6c811c-battery unit_of_measurement: '%' device_class: battery state_topic: miflora/sensor/elastica1/state value_template: '{{ value_json.battery }}' device: identifiers:

Hey! I agree with the idea but didn't test so far. Any feedback from your side?
