AsyncWorker assumed that after work is complete, a JavaScript callback would need to execute.

This change removes the restriction of specifying a Function callback, and instead replaces it with an Env parameter. Since the purpose of receiver was for the this context for the callback, it has also been removed from the constructors.

These should be Napi::Env env as opposed to napi_env env for consistency with the rest of the API. Same goes for other places env is being added.

Thanks for the tip. I was a little confused because several places use napi_env but maybe those are older pieces of code. Changed now to Napi::Env

`AsyncWorker` assumed that after work is complete,  a JavaScript
 callback would need to execute.

This change removes the restriction of specifying a `Function` callback,
and instead replaces it with an `Env` parameter. Since the purpose of
`receiver` was for the `this` context for the callback, it has also been
removed from the constructors.
