This simplifies the setup for transactional producing and committing, no longer requiring a custom rebalance listener or the use of `partitionedAssignmentStream`. See `ConsumerSpec` for an example. Note that the transaction ID is no longer used for fencing since https://cwiki.apache.org/confluence/display/KAFKA/KIP-447%3A+Producer+scalability+for+exactly+once+semantics, the mechanism relies on the consumer group metadata instead. NOTE This change is not binary compatible and is therefore, for zio-kafka 3.0.0

Introduce a much simpler way to use the transactional producer. It is no longer needed to install a complex rebalance listener, coupling your
TransactionalProducerto aConsumeris enough.See #1432 for documentation.
