Added

• Support for std::format (if available). Instances of intrusive_shared_ptr can be passed to std::format
  and will be printed like a void *.
• Support for std::hash<intrusive_shared_ptr>.
• get_inout_param() method. This provides the same functionality as std::inout_ptr but is available for pre-C++23 compilation.

Changed

• Performance improvements for std::out_ptr etc.
• C++ module is no longer using CMake library mechanism. See README for details on how to use module.

Fixed
