Buffer Render method incorrectly assumes all native data formats have 8bit elements

[Makuna]

Describe the bug In the NeoPixelBufferShader.ino example, the shader implementation has two uint8_t* parameters that represent the pixel color; and assumes that each byte is a distinct element. There are several features that this is not true. This demonstrates a design flaw in how "buffers" implement shaders and they are different in how "DIBs" implement them.

Expected behavior The shader implementer should be given a standard color object and not a stream of bytes like how DIBs shaders work.

Additional context Buffer.h, Render should look like

    template <typename T_SHADER> void Render(NeoBufferContext<typename T_BUFFER_METHOD::ColorFeature> destBuffer, T_SHADER& shader)
    {
        uint16_t countPixels = destBuffer.PixelCount();

        if (countPixels > _method.PixelCount())
        {
            countPixels = _method.PixelCount();
        }

        for (uint16_t indexPixel = 0; indexPixel < countPixels; indexPixel++)
        {
            typename T_BUFFER_METHOD::ColorObject color = shader.Apply(indexPixel, _method.GetPixelColor(indexPixel));
            T_BUFFER_METHOD::ColorFeature::applyPixelColor(destBuffer.Pixels, indexPixel, color);
        }
    }

But at this point, these non-DIB renders become more expensive than DIB renders as the bytes need to be converted to a DIB Color, manipulated in the shader, and then converted back to native format. With this then, why have native shaders at all?
