Extend the LargeResponseHandler middleware to support more use cases

[jpinho]

What was built regarding the Large Response Lambda Middleware is a great all-in-one solution for one specific lambda use case:

• API Gateway with Lambda Proxy Integration

Although, while we at epilot use this pattern a lot, it's by no means the only way Lambda is used.

The same 6MB response limit applies in all Lambda use cases. Just to give some examples that are not covered by this middleware:

• Lambda function URLs
• Lambda in Step Functions
• Direct Invoke via Lambda API
• API Gateway Lambda service integration
• Lambda@Edge

Since the 6MB limit applies anywhere, we could build and publish something more generic that works for all Lambda use cases (not just this one).
