Is there an existing issue for this?

Current behavior

I want to send back from my method decorated with MessagePattern/EventPattern data with NATS headers and turns out that they're not passed in any way.

I tried with setting

@MessagePattern('abc')
method(@Ctx() context: NatsContext) {
  ctx.getHeaders().set('response-header', 'abc')
  return 'my data';
}

with hope that they will be applied but with no luck - they're undefined 😂

Expected behavior

I would expect that @Ctx() context: NatsContext will have method setResponseHeader and in ServerNats.getPublisher method it will apply them to packet and default serializer will handle it:

// line 26 of nats-record.serializer.ts
: new NatsRecordBuilder(packet?.data).build()

// new line 26 of nats-record.serializer.ts
:  new NatsRecordBuilder(packet?.data).setHeaders(packet?.headers).build()

I'm open for any solution and even preparing PR (but I will need some help with preparing the solution)
