Error when int[] has group+2 elements

[nobre84]

Hi, first, thank you for the effort on posting the project up!
I found an issue when the encoded array has group + 2 elements (6, 10, 14, etc)

I fixed by changing:

    switch (length - idx)
    {
        case 3: encodeGroup(buff, values[idx], values[idx++], values[idx++], 0);
        case 2: encodeGroup(buff, values[idx], values[idx++], 0, 0);
        case 1: encodeGroup(buff, values[idx], 0, 0, 0);
    }

to

    switch (length - idx)
    {
        case 3: encodeGroup(buff, values[idx++], values[idx++], values[idx++], 0);
        case 2: encodeGroup(buff, values[idx++], values[idx++], 0, 0);
        case 1: encodeGroup(buff, values[idx++], 0, 0, 0);
    }
