BundleToResources adjustment and optimization (#543)

* Outputting to folders named after the initial bundle. Still more work to do, checking in progress.

* Maintaining complete folder structure including subdirectories.

* Cleaned up the output a bit, added some logical rules for when to skip processing of files (not json or xml, or matches output path)

* Multithreaded support added and adjusted default Executor in ThreadUtils to avoid memory issues on macos

* saving

* Removed folder structure where files are extracted to a folder named after the bundle, but folder structure of where files originate from is retained.

* Adjusting the ThreadUtils thread pool count

* Optimized BundleToResources, added new argument db (delete bundles) to run use -db=true, updated test with new delete feature.

* Cleanup

* Correcting some path issues stemming from a windows vs macos file system. Also correcting an issue where a reused instance of BundleToResources() was erroneously passing in -db=true to a test that shouldn't have it.

* Backing out ThreadingUtil adjustment to make standalone PR for it.
