Introduce a JsonBytesToMap as a part of a payload-converter-function module which is auto-discovered by Spring Cloud Function scanning algorithm - the functions package.
Add a payload-converter-function as dependency into an aggregator-function
Compose jsonBytesToMap|aggregatorFunction for the aggregator-processor
Verify a JsonBytesToMap function in action with an AggregatorProcessorTests
Mentioned such a payload conversion in the aggregator-processor README
Fixes https://github.com/spring-cloud/stream-applications/issues/441
