refactor: remove references to deprecated values under std::allocator

Browse source 
Includes allocator::pointer, allocator::const_pointer, allocator::reference and allocator::const_reference which are deprecated in c++17 and removed in c++20. See https://en.cppreference.com/w/cpp/memory/allocator

Also prefer `using` over `typedef` see: https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using
