PrintingOutput as alternative to StreamingOutput

[dblevins]

Getting quite tiresome to always do:

    @Command
    public StreamingOutput list() {
        return new StreamingOutput() {
            @Override
            public void write(OutputStream os) throws IOException {
                final PrintStream printStream = new PrintStream(os);
                // use the printStream 
            }
        };
    }

For backwards compatibility we should add a new interface PrintingOutput

package org.tomitribe.crest.api;

import java.io.IOException;
import java.io.PrintStream;

public interface PrintingOutput {
    void write(PrintStream out) throws IOException;
}

@Command
public StreamingOutput list(@Out PrintStream printStream) {
    return new StreamingOutput() {
        @Override
        public void write(OutputStream os) throws IOException {
            // use the printStream 
        }
    };
}

or simply (likely more relevant since we dont have output events and it allows to keep interceptor context vs write(out) which lost it):

@Command
public void list(@Out PrintStream printStream) {
    // use the printStream 
}

?

side note: OutputStream from StreamingOutput is already a PrintStream so you can cast it too.
