Changing C++ Compile Version

[CursedRock17]

This is a small pull request directly related to issue #75 that will update the compiler from compiling with standard C++11 to C++17, which should resolve small errors on MacOS arm64 as a guarantee that std::variant works. This change would also require a similar update the CXX version in the performance_test_fixture package as mentioned in the above issue.
