Subject: [PATCH] Decompile 4 functions in
 Source/Resource/Models/ModelResourceV2.cpp,
 Source/Resource/Models/ModelResource.h

Batch #11599 by SapitoSucio: 0 byte-identical, 4 confirmed by peer review.

- fn_07954 C3dModelResV2::Load: logic confirmed by peer review
- fn_08020 C3dModelResV2::ReadVersion1: logic confirmed by peer review
- fn_08021 C3dModelResV2::ReadVersion2: logic confirmed by peer review
- fn_08022 C3dModelResV2::ReadVersion3: logic confirmed by peer review

Peer-reviewed-by: Yommy, KWDev, cremane
Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes).
