Support for PackageDependency

[tapaolo]

Hi, great job with the project! I don't know if this feature is already there but anyway...

WinGet supports the concept of PackageDependency in its manifest. We can use it to provide a Package Identifier and an optional minimum version for packages the application requires to be installed prior to running its installer.

winget would eventually first install all the required dependencies and finally the package we requested to install.

Does wingetty support this feature ? If not available through the UI, it would still be very useful if it could be supported by directly editing the manifest.
