[JDK9+] package org.aesh.io split in two jars

if you have aesh-1.0.jar and aesh-readline-1.3.jar
on your module path, jvm complains as both jars export package org.aesh.io
which violates the modules contract where only one module (jar) can provide single package.

example error that jvm prints

java.lang.module.ResolutionException: Modules aesh.readline and aesh export package org.aesh.io to module jboss.marshalling.river

same issue applies for packages

org.aesh.readline
org.aesh.util
org.aesh.io
