Improve deploy_windows.ps1 fetching of dependencies

Updated Install-Dependency to create a unique empty directory for
unpacking the fetched zip file into, for ASIO and NSIS.

This avoids having to know the top-level directory name used within
the archive, which for ASIO is not consistent between versions.
