Use local isos fixed (#361)

* Start adding params for existing isos

* Merge parameter handling code

* initial testing seems reasonable

Note that if copying files in, "wget -c " will assume

smaller-than-remote files are parts and continue
so likely will cause hashing failures
or if no hash check then corrupt isos.

* Added usage for --help

* Usage enhanced and added to Readme

* spurios unused cruft removed

* Fixed race

adding belts and braces

* Removed debugging and cruft

* Not yet able to cache windows because windows

* Working for cached macos

with limitations
