Allow axes_type which inherits from std::vector<...> #254

Closed HDembinski closed 4 years ago

Currently, users cannot customize the two possible axes types based on std::tuple and std::vector. It would be nice to at least support types inherited from std::vector<axis::variant<...>>, because this allows one to hide the large type name from compiler error messages and in signatures.

conclusion after more thought: this does not work
