BundleToResources adjustment and optimization

[echicoine-icf]

Changes:

• Retain folder structure to easily trace source of extracted resources
• Added new argument handling to delete bundles after operation completes: -db=true
• Added new BundleToResources test to account for new delete bundle argument
• Optimized code to handle large file loads
• Adjusted ThreadUtils after discovering macOS/linux does not handle cached executor as Windows does. Executor set to fixed thread pool (cpu core count * 2)
