That way we don't need to decode to QString in order to compare to "Keys". There's no avoiding the conversion to it when inserting in the map for top-level elements, but use of moc's -M option is extremely rare. Ideally, we'd simply ask QCborStreamReader to perform a comparison to a string of ours, so we didn't have to memcpy from the stream in the first place. But TinyCBOR has no API for that (it's been pending as https://github.com/intel/tinycbor/issues/223 for a while).
