/**
 * Represents an MQTT Camera component for Home Assistant MQTT Discovery.
 *
 * The `mqtt` camera platform allows you to integrate the content of an image file sent through MQTT into Home Assistant as a camera.
 * Every time a message under the `topic` is received, the image displayed in Home Assistant will be updated.
 * Messages received on `topic` should be the full contents of an image file, e.g., a JPEG image, without additional encoding or metadata unless `image_encoding` is used.
 *
 * For detailed documentation see:
 * https://www.home-assistant.io/integrations/camera.mqtt/
