change binding.gyp for mac for build the package

[gentilmente]

I`m not an expert, sorry if this is not the correct way of ask for this change. It solved me a building problem.

'cflags': [ '--std=c++11' ],

'OTHER_CPLUSPLUSFLAGS' : [ '-std=c++11',

In both cases change it to 14

My system:
mac osx 12.0.1
updated xcode cli tools
node 14.16.0

In the same direction, in order to be able to upgrade node to v16 you need to folow these instructions

in bining.cc:

extern "C" {
  NAN_MODULE_INIT(init) {
    Nan::HandleScope scope;
    GPhoto2::Initialize(target);
    GPCamera::Initialize(target);
  }

  #if NODE_MAJOR_VERSION >= 10
  NAN_MODULE_WORKER_ENABLED(gphoto2, init)
  #else
  NODE_MODULE(gphoto2, init)
  #endif
}
