    avcodec/dpxenc: reject unsupported depths for RGB48 input

    Only 10 and 16 bit output exist for RGB48, reject everything else
    at init.

    Fixes: NULL pointer dereference
    Fixes: cPU32SjSff6g
    Fixes: AISLE-2026-0150-00374
    NULL pointer dereference Replicated through UnModified FFmpeg with ASAN
