FPackageStoreBulkDataManifest:: Data ** is not sorted. It generates a difference,

Here's a workaround

void FPackageStoreBulkDataManifest::Save()
	TUniquePtr<FArchive> BinArchive(IFileManager::Get().CreateFileWriter(*Filename));

	// Take the versions from the archive and serialize them out
	// NOTE: Serializing out now means we cannot add additional versions while serializing
	// it is assumed that we are only using FBulkDataManifestVersion::GUID
	FCustomVersionContainer CustomVersions = BinArchive->GetCustomVersions();

	Data.KeyStableSort([](const FString& A, const FString& B){	return A < B;	}); //workaround
	*BinArchive << Data;

Steps to Reproduce
  1. Create a project
  2. Package the project
  3. Copy Saved/Cooked/S witch/[ProjectName]/Metadata/BulkDataInfo.ubulkmanifest to a different location
  4. Package the project again
  5. Diff the asset files

Result : 

There is a difference between the two files
