Please describe your feature request:

Subfinder can be used as a golang library as per the example here. Currently, it performs enumeration against the given target and returns all the results after it is done. It would be nice to have the results written to a channel in realtime, allowing client libraries to receive subdomains as they are discovered.

Describe the use case of this feature:

I'm writing a tool that integrates multiple tools in a recursive fashion, and the sooner I can stream outputs to other downstream tools, the faster my whole pipeline becomes. I currently use naabu for port scanning and naabu had an option to consume results as soon as they are available, by providing an OnReceive callback. I would love for subfinder to provide the same.
