Pipe targets are the end point of a EventBridge Pipe.

### Amazon SQS
TODO

A SQS message queue can be used as a target for a pipe. Messages will be pushed to the queue.

```ts
declare const sourceQueue: sqs.Queue;
declare const targetQueue: sqs.Queue;

const pipeTarget = new targets.SqsTarget(targetQueue);

const pipe = new pipes.Pipe(this, 'Pipe', {
source: new SomeSource(sourceQueue),
target: pipeTarget
});
```

The target configuration can be transformed:

```ts
declare const sourceQueue: sqs.Queue;
declare const targetQueue: sqs.Queue;

const pipeTarget = new targets.SqsTarget(targetQueue,
{
inputTransformation: pipes.InputTransformation.fromObject(
{
"SomeKey": pipes.DynamicInput.fromEventPath('$.body')
})
}
);

const pipe = new pipes.Pipe(this, 'Pipe', {
source: new SomeSource(sourceQueue),
target: pipeTarget
});
```
