Windows Performance Improvement & Multi-Item support (#43)
* Initial IFileOperation for Windows - Try using IFileOperation instead of SHFileOperation - Use pywin32 to accomplish this - Implement fallback when pywin32 not available - Handles paths like `C:\` just fine bu the `\\?\` paths in the test cause issue - Add batching for IFileOperation version (performance) - Minor formatting applied by editor * Fix issue with paths starting with \\?\ - Strip these characters off if present just like old implementation * Add windows version check, legacy list support - Add check for windows version for IFileOperation - Add list support to legacy version - Remove some debugging code - Fix bug in path converson Not sure if there is a better way to layout this file * Split plat_win into legacy and modern * Update other platforms for list support Formatter also ran on these so some other minor changes. * Add unit tests for multi-file calls
