Update target c++ standard to 17 to support new MacOS

[tripheo0412]

Building on Mac M1 using Node 18 is fine. When building on Node 19 or 20 we got an error due to incompatible with C++17 Issue #186

Solution is to force newer c++ 17 standard for complier instead of the old one c++ 14. Edit binding.gyp
