install script in package json causes silently exit package installation with code 0 even in case of error

[s-a]

https://github.com/openvenues/node-postal/blob/master/package.json#L34
"install": "(node-gyp rebuild) || (exit 0)", -> "install": "node-gyp rebuild"

After fixing this i get
libpostal/libpostal.h not found

you need to install the libpostal library
