Hey @damiencarol @Maffooch, thanks very much for taking the time to review. All requested changes implemented. I initially followed the guide, and created the parser using cookiecutter https://github.com/DefectDojo/cookiecutter-scanner-parser, which is what created all that additional code.. I wasn't sure if it was needed..
