Allow Categories to split the output table into several smaller tables

[UlisesGascon]

As discussed in nodejs/security-wg#949, it will great to allow the repos to we categorized like primary, secondary.. so the output table can be split into several minor tables. That way is easier to focus only in a specific repos when the discovery mode is enabled. That way the user can control easy all the repos in a specific organization and segment the results for the analysis.

@KoolTheba This is very related to #35 but is a different feature
