two change:
* remove use of `register` in `md5.cpp`
* remove use of `using namespace std` in `Core.cpp` (which causes an ambiguous name resolution error between `byte` and `std::byte`). while there are other ways to resolve this, `using namespace std` is a code smell anyway, so eliminating it is the best option
