Serverless Stack

In your stack, define these at the top
```import * as s3 from '@aws-cdk/aws-s3';
import * as sst from "@serverless-stack/resources";
import { S3EventSource } from '@aws-cdk/aws-lambda-event-sources';```

And the code looks something like this. Configure the bucket, and the bucket events u want to trigger the Lambda with.
```const bucket = new s3.Bucket(this, "MyBucket");
const lambda = new sst.Function(this, "MyFunction", {
	handler: "src/myFunction.main"
});
lambda.addEventSource(new S3EventSource(bucket, {
  events: [ s3.EventType.OBJECT_CREATED, s3.EventType.OBJECT_REMOVED ]
}));```

We will create an `sst.Bucket` construct later to simply this
