Add chunked transfer demonstration and test framework

- Create Demo-ChunkedTransfer.ps1 for showcasing implementation
- Add PSMinIO-TestFunctions.psm1 with test functions
- Add Test-ChunkedModule.ps1 and Quick-Test.ps1 for validation
- Update Build.ps1 to output to Artifacts directory
- Remove unnecessary progress parameters (use standard ProgressAction)
- Add missing using statements for compilation
- Create test manifest PSMinIO-Test.psd1
- Ready for C# compilation and integration testing
