Intermediate output file can grow too large

Can I make a pull request for this?

@faizal3199 actually the issue is that massdns full output is needed by the parser to correctly parse the output and handle various cases of DNS resolution like multiple CNAMES, NS, etc.

The parser that shuffledns uses is currently https://github.com/projectdiscovery/shuffledns/tree/master/pkg/parser. If you can figure out a way to make it work without breaking other things, that would be great for sure!

@Ice3man543 I looked through parser's code. With --output option set to Snl, massdns will add an extra newline between two different DNS replies, thus adding an empty line and allowing shuffledns to differentiate between two DNS answer section.

As for handling A, NS and CNAME records, the code logic needs not to be changed much.

@faizal3199, thanks for looking into it so quickly. That makes sense, using Snl mode. This is not on our priority list for now, but if you want to make a PR to add this feature, by all means go for it. I'd be more than happy to help you getting it merged!

Nice work @faizal3199. I tested and it worked well.
