provide a callback-based invocation

[MaxDesiatov]

Currently it seams unclear on how to use this library with other promises implementation, such as Q, because es6-promise is incompatible with Q. It would be nice if avprober presented a simple callback invocation in its API, so that library clients could adapt it to their promise implementations as needed.

You're probably right.

I think it would be alright to add optional callback arguments to the main function, and still return the standard es6 promise.
