Prerelease 0.33.0-alpha.5

If you want to build sharp from source against a globally-installed
libvips then you will now need to add both node-addon-api and
node-gyp to the dependencies section of your package.json file.

The binding.gyp file is "hidden" inside the src directory to
prevent various build and package manager tooling from assuming
that everyone is going to build from source every time.
