🚀 Feature

• Add script to sort out external Java jar libraries. This script comes in handy when you've extracted all jar files of an application that also contain external libraries and you want those to be sorted out so that they don't get analyzed directly. This save space and resources and helps to clearly distinguish internal from external libraries in your data.
