Keep a variable to add the sizes of subdirs

auto dFiles = dirEntries(i, SpanMode.shallow).filter!(a => 
a.isDir && !globMatch(a.baseName, "*DND*")).array;
ulong subdirTotal = 0;
foreach (d; dFiles)
{
         subdirTotal = 0;
         auto SdFiles = dirEntries(d, SpanMode.depth).array;
         foreach(f; SdFiles) {
                 subdirTotal += f.size;
         }
         writeln(d, "\t", subdirTotal);
}
