test with Vector type instead of Array (Virgil)

var imgProc = ImgProc.new(width, height, channels);
var inputData_size = width * height * channels;
var internal_data: Vector<byte> = Vector<byte>.new();
for (i = 0; i < inputData_size; i++) {
internal_data[i] = (inputData + i).load<byte>();
}
return Pointer.atContents(imgProc.grayscale(internal_data));
