+/**
+ * Bambda Script to Detect "Content-Security-Policy-Report-Only (CSP-RO)" Header in HTTP Response
+ * @author ctflearner
+ * This script checks if the HTTP response contains the "Content-Security-Policy-Report-Only" header, 
+ * which is used for monitoring CSP violations without enforcing restrictions. 
+ * Additionally, it verifies if the header specifies a "report-uri" directive, 
+ * indicating where CSP violation reports are sent.
+ * The script ensures there is a response and scans the headers for these conditions.
