Add an AWS Lambda Generator

[SentryMan]

People tend to make apis with lambdas, why not have the plumbing be automated by a code generator?

People should be able to write:

@Controller("/widgets")
public class WidgetController {
  private final HelloComponent hello;
  public WidgetController(HelloComponent hello) {
    this.hello = hello;
  }

  @Get("/{id}")
  Widget getById(int id) {
    return new Widget(id, "you got it"+ hello.hello());
  }

  record Widget(int id, String name){};
}

And have the lambda (de)serialization and routing code generated.

We're gonna need:

• Some sort of Router Class that'll match the routes
• A Json Interface for (de)serializing the body
• Interfaces for wiring
• support for both API Gateway and ALB

After all of that, we can start generating the code to hook into this.
