AOA FMTV Engine Sound Fix

BTGG Strider Vehicle Fix overrides the M1083 engine audio with a version that references Vehicles_M1083_Engine_Turbo.wav, which WCS_FMTV removed in its July update. The whole engine sound then fails to compile. This mod restores the current WCS_FMTV engine audio and loads after BTGG. Load order: WCS_FMTV, BTGG Strider Vehicle Fix, this mod.
