did some reorganization, build script changes

Moved header and source to code

Changed all build scripts to just be powershell (preferred)
Added clang format (but forgot that you cannot format zpl because it hangs clang format)

Code changes:
* Removed long names just using short names (there is an issue with the opts_compile...)
* Removed zpl.refactored.h (its generated now when `.\build.ps1 test` is run
* Modified zpl.h to just have the radix sort modification.
