A Node-RED node for making predictions with Cloud Annotations models.
Run the following command in your Node-RED user directory - typically ~/.node-red:
npm install node-red-contrib-cloud-annotations

msg.payload: The payload can either be a string path to an image file or a buffer object holding the image bytes.
msg.payload: A list of predictions.
The prediction array varies depending on the type of model loaded.
