Image size limit

[bluedoors]

The Streamlit application suggest files of up to 200MB can be uploaded. However the image is subsequently sent to api-gateway to Rekognition for label detection and therefore the api-gateway payload size is limited to 10MB causing files larger than that to return an HTTP 413. There is also no error handling on the api-gateway request so it manifests itself as a stack trace "json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)" on the reponse.json() call
