Subject: [PATCH] Update workflow for #19

This will update the workflow to allow the following:

1. Override the revisions and not compute them.
1. Override the prefix and ignore overridden revisions.
1. The default, add prototype* as a prefix for publication from the
usnistgov/OSCAL repo.

In the case the last scenario is not desired, a developer with admin
permissions in the repository can provide a '' prefix and all prototype
prefix branches go away and will be silently ignored.
