No graceful shutdown i.e. no way to stop naabu from scanning except killing the process

[a-urth]

Naabu version:

v2, using as library

Current Behavior:

Naabu upon call to RunEnumeration spawns bunch of workers to perform scanning in background and blocks until it finishes. Using it as a library with other operations running in background (like processing any other form of input) there is no way to stop it except killing process which it running in.

Expected Behavior:

There should blocking method Stop in case naabu is running concurrently with other goroutines which will gracefully stop all workers.
