Function lambda_flows::request_received

pub fn request_received<F>(cb: F)where
    F: Fn(HashMap<String, Value>, Vec<u8>),

Register a callback closure with the query and body of the request for the lambda service.

The query is formed as a HashMap. For example, say the entrypoint of the lambda service is https://code.flows.network/lambda/6rtSi9SEsC?param=hello then the query will look like HashMap("param", Value::String("hello"))

The body is the raw bytes of the request body.
