add normal maps for tyddys arkitektora 2.0

Tyddys arkitektora 2.0 mods (vivec and hlaalu) don't support the normal maps used in the other mods. Normal maps are provided by another user on nexusmods Additionally i have fixed a mistake in the vivec file. The archive names of HQ and MQ Sources were switched (HQ was used for low resolution and MQ for high, leading to failling install) Signed-off-by: Jan Thomas jan.thomas.118@gmail.com
