Using Node-API from a classic addon module

[segevfiner]

As a stop-gap for compatibility, I wanted to try and create a module that converts v8/NaN tree-sitter language object (Which is a v8::Object with an internal pointer) to a napi language object (A type tagged Napi::External).

Such a module is technically a classic Node ABI dependent module, so should use the NODE_MODULE way of init so that Node.js will properly block it from loading if built agains't the wrong version, as it is going to use v8/NaN API to access the v8/Nan language object, but then since I don't have a napi_env, I can't create the napi external or use napi at all from such a module.

On the other hand, if I use the NAPI_MODULE, then Node.js will likely agree to load such module across different ABI versions even if it technically depends on a specific Node.js ABI version, but I will have a napi_env and can technically use v8 API from a Node-API module by way of v8::Isolate::GetCurrent and friends.

Is there a supported way to create such a module?
