• Here, intendet to be used for std::array (for which std::tuple_size works), for other COMMUNICATEE types, a different static size retrieval should be implemented.
• Actually, vector might also work here, however is unfortunately rather passed to ConcreteCommunicatable<std::vector<COLUMN>>
• TODO: Include properly into complete framework, if found usefull. Get serialized size for complete data
