Track Java "shaded"/uberjar/jarjar hidden dependency vulnerabilities

See:
- https://github.com/jensdietrich/xshady and https://github.com/jensdietrich/xshady-release/ by @jensdietrich et al. and paper at https://arxiv.org/abs/2306.05534
- we have some PurlDB WIP on Uberjar detection and related issues at:
- https://github.com/nexB/purldb/issues/154
- https://github.com/nexB/purldb/issues/69
- https://github.com/nexB/purldb/issues/98
- https://github.com/nexB/scancode-toolkit/issues/2418

@jensdietrich I read "Those projects were detected with a research tool our team has developed" ... is this open source?
