Implement CloudWatch alarm SNS payloads.

calavera commented 6 months ago

Issue #, if available:

Fixes #793

Description of changes:

Add the struct definitions based on the Go events: https://github.com/aws/aws-lambda-go/blob/3a93ed1e265b5e368f0d20c3a2b8395d2c9f787d/events/sns.go#L34-L88 It doesn't look like the Java and Dotnet events implement these structs to verify them, but the tests are able to deserialize the example payloads that we've been testing already.

I was too slow... thanks for the addition.

no worries. I'm planning on doing a release, and I thought they could just be there.
