refactor the cacher to reduce complexity, removes the access guarantees (relaxed,immediate,...), uses the fact that other tasks will wait on atomic value change for the cache-pointer if it is nullptr to add the entry to cache structure earlier reducing cost of two threads accessing new entry at the same time, splits the offloading-cache.hpp file into two with one containing the data-class (represents a cache entry and task) and the other containing the cacher itself
