Baseline support

[KevinHock]

Once #100 is merged this will be do-able.

So a baseline is for when you want to diff between a previous run, (probably of known issues or false-positives) and a current run, 'as a big part of continuous integration', baseline support is super important.

See https://github.com/openstack/bandit as a tool that implements this.

    parser.add_argument('-b', '--baseline',
                        help='path of a baseline report to compare against '
                             '(only JSON-formatted files are accepted)',
                        type=str,
                        default=None)

There is also the newly open sourced detect-secrets repo from the Yelp security team that implements this.
