New version uses functions not macros. The use of template functions allows for enforcement of type-safety, which is implemented using static_assert. The old implementation is preserved for posterity. A header guard was added. I found the old macro names confusing, so I used new names, but I map the old names in the source onto them so the application source does not change.

This improves on #43 by adding a potentially universal implementation of atomics using C++20 atomic_ref.
Not everyone supports this right now but if compilers don't lie with feature test macros, the preprocessor will inform the user effectively.
