Summary of Changes

Hello @gcatanese, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new event type, ScanBarcodeResult, to the system's event notification mechanism. This enhancement allows the system to communicate the results of barcode scanning operations, providing clearer feedback on whether a scan was successful or timed out. The change primarily involves extending an existing enumeration to support this new event.

Highlights

• New Event Type Added: The EventToNotifyType enum in src/main/java/com/adyen/model/nexo/EventToNotifyType.java has been updated to include a new event type: SCAN_BARCODE_RESULT. This new type is intended to deliver the outcome (result or timeout failure) of a barcode scan operation.
