This API endpoint allows you to retrieve reviews for a specific restaurant on Yelp and process the review data using the Yelp API. The endpoint takes a parameter that specifies the ID of the restaurant, and returns a list of reviews in JSON format.

For each review, the API endpoint also processes the reviewer's avatar image using the Google Vision API to extract emotions data such as joyLikelihood and sorrowLikelihood. This data is included in the JSON output along with the review information.
