oscap-dockerless -- oscap wrapper for saved Docker images

TL;DR

$ docker run -v `pwd`:/mnt/data -ti gerald1248/oscap-dockerless \
  oscap-dockerless /mnt/data

This invocation assumes that one or more saved Docker images are stored in the working directory. The output is written out alongside the input tarfiles.

Assuming there is an archive centos7-unpatched.tar in the working directory, the output would be as follows:
