    Macro to enable bitwise operations for scoped enums (enum struct/class).

    To use this, add the line JUCE_DECLARE_SCOPED_ENUM_BITWISE_OPERATORS (MyEnum)
    after your enum declaration at file scope level.

    e.g. @code

    enum class MyEnum
    {
        one     = 1 << 0,
        two     = 1 << 1,
        three   = 1 << 2
    };

    JUCE_DECLARE_SCOPED_ENUM_BITWISE_OPERATORS (MyEnum)

    MyEnum e = MyEnum::one | MyEnum::two;

    bool hasTwo = (e & MyEnum::two) != MyEnum{}; // true
    bool hasTwo = hasBitValueSet (e, MyEnum::two); // true

    e = withBitValueCleared (e, MyEnum::two);

    bool hasTwo = hasBitValueSet (e, MyEnum::two); // false
