struct ProducerConsumerSynchronization
Synchronizes one producer with a consumer.
The producer checks if the consumer is ready (previous work is finished), it prepares the data for the consumer, and signals the consumer.
On its side, the consumer waits for data to be computed and applies a function as soon as the data is ready
