AI Summary: Add a feature flag to the `aws_lambda_events` crate that allows for a 'catch-all' field (a `Map<String, Value>`) to handle unmodeled or undocumented fields in AWS Lambda events. This would improve flexibility and future-proofing, allowing users to access new or undocumented fields without requiring immediate updates to the crate.

AI Summary: Verify that all event structures within the `aws_lambda_events` crate have the `#[derive(Default)]` attribute implemented. This ensures that default instances of these event structures can be easily created for testing and other purposes.
