Allow whitelisting of jars in the JDK/JRE lib/ or ext/ directory, even when system jars are blacklisted, using (in the scan spec) strings of the form "lib:myjarname.jar" / "ext:myjarname.jar".
Also allow whitelisting or blacklisting of modules to scan, using "mod:com.xyz.modulename" for whitelisting or "-mod:com.xyz.modulename" for blacklisting.
