IsMorphAvailable improvements

[Noggog]

Analyzers trying to determine if IsMorphAvailable for IMorph objects is clunky and requires bit analysis

public static bool IsMorphAvailable(this IMorphGetter morph, uint index)
{
    var div = (int)index / 8;
    var mod = (byte)(index % 8);
    var data = morph.Data[div];
    return (data & (1 << mod)) != 0;
}

Can probably upgrade it to be an array of bools or something similar
