Support for JSON output

[NotoriousRebel]

Having JSON output as an option would be nice, especially when doing -l targets.txt, for example

{"x.subdomain.com" : ["new.subdomain.com",  "second.subdomain.com", "etc.."]}

Just mapping the specific taarget to the domains found from CSP.

Hi @NotoriousRebel,

I'm trying to add support for JSON.
The devel branch (https://github.com/edoardottt/csprecon/tree/devel) contains the modifications applied to add support for JSON.

Please test it and see if you spot some weird behaviour or it's okay for you.

Normal output (-j flag not specified)

Try with

echo URL | go run cmd/csprecon/csprecon.go

or

cat URLs.txt | go run cmd/csprecon/csprecon.go

JSON output (-j flag specified)

Try with

echo URL | go run cmd/csprecon/csprecon.go -j

or

cat URLs.txt | go run cmd/csprecon/csprecon.go -j

Consider that I didn't add code to support usage of JSON output with other flags. This means json output could break CIDR, File output flag etc..
