[Feature] Creating non-flat msixbundles

[Abdiramen]

Whenever you try to create a bundle (that isn't flat) it will fail because this piece of code is not implemented

msix-packaging/src/msix/pack/AppxBundleWriter.cpp

Lines 117 to 121 in efeb9da

	HRESULT STDMETHODCALLTYPE AppxBundleWriter::AddPayloadPackage(LPCWSTR fileName, IStream* packageStream) noexcept try
	{
	// TODO: implement
	NOTIMPLEMENTED;
	} CATCH_RETURN();

Is there any plan to implement this? I need it so that I can create .msixbundles that are suitable for the msstore. I would be happy to implement this for you but would need some direction

This is a pull request that implements that functionality...
