(core): sheldon doesn't indent properly enum class

Summary

Uncrustify does not indent properly enum class when using std::uint8_t. It works with int.

Steps to reproduce

    enum class Attributes : std::uint8_t
    {
        NONE                 = 0,
        POINT_COLORS         = 1 << 1,
            POINT_NORMALS    = 1 << 2,
            CELL_COLORS      = 1 << 3,
            CELL_NORMALS     = 1 << 4,
            POINT_TEX_COORDS = 1 << 5,
            CELL_TEX_COORDS  = 1 << 6
    };

See Mesh.cpp:305
