Converting compressed BMP RLE4

Both loading and saving of the Rle4 compressed Bmp images are supported.

try (Image image = Image.load("Rle4.bmp"))
{
	BmpOptions options = new BmpOptions();
	options.setCompression(BitmapCompression.Rle4);
	options.setBitsPerPixel(4);
	options.setPalette(ColorPaletteHelper.create4Bit());
    
	image.save("output.bmp", options);
}
