uvm_move_dir

Opinionated directory move operations. The default rename operation from std::fs::rename doesn't work for some usecases uvm has during installation of certain modules. The special move_dir function in this crate allows:

• to move files into the same path.
• rename directories

A special windows invocation of MoveFileExW without the MOVEFILE_REPLACE_EXISTING flag, which std::fs::rename sets, allows moving of directories also under windows.
