IMAGINGJAVA-9300 Error on converting TIFF to PNG

Convert Tiff to other format without metadata:
public void convert(String sourceImageFile, String outputImageFile, ImageOptionsBase outputImageOptions)
{
    try (Image image = Image.load(sourceImageFile))
    {
		image.removeMetadata();

		if (outputImageOptions == null)
		{
			image.save(outputImage);
		}
		else
		{
			image.save(outputImageFile, outputImageOptions);
		}
	}
}

IMAGINGJAVA-9289 Implement VectorImage.Create method that provide the ability to create a vector image without specifying its format.

## Create a new vector image, draw some figures and text, and save it into SVG, EMF, WMF, PNG files.

try (VectorImage image = VectorImage.create(1000, 1000, GraphicsUnit.Pixel))
{
    Graphics deviceContext = new Graphics(image);
    deviceContext.setPageUnit(GraphicsUnit.Pixel);

    SolidBrush brush = new SolidBrush(Color.getYellow());
    Pen pen = new Pen(Color.getBlue());
	
	deviceContext.fillPie(brush, new RectangleF(10, 10, 80, 80), -270, 270);
	deviceContext.drawPie(pen, new RectangleF(10, 10, 80, 80), -270, 270);

	deviceContext.drawArc(pen, new RectangleF(100, 10, 80, 80), 180, 90);

	deviceContext.fillEllipse(brush, new RectangleF(200, 10, 80, 80));
	deviceContext.drawEllipse(pen, new RectangleF(200, 10, 80, 80));
	deviceContext.fillRectangle(brush, new RectangleF(300, 10, 80, 80));
	deviceContext.fillRectangle(brush, new RectangleF(400, 10, 80, 80));
	
	deviceContext.drawString("Hello World!", new Font("Arial", 16, FontStyle.Bold), new SolidBrush(Color.getBlack()), new PointF(10, 110));
	image.save("output.svg", new SvgOptions() {{
		setVectorRasterizationOptions(new VectorRasterizationOptions() {{ setBackgroundColor(Color.getEmpty()); }});
	}});
	
	image.save("output.wmf", new WmfOptions() {{
		setVectorRasterizationOptions(new VectorRasterizationOptions() {{ setBackgroundColor(Color.getWhite()); }});
	}});
	
	image.save("output.emf", new EmfOptions() {{
		setVectorRasterizationOptions(new VectorRasterizationOptions() {{ setBackgroundColor(Color.getEmpty()); }});
	}});
	
	image.save("output.png", new PngOptions());
}

IMAGINGJAVA-9288 BMP: Add support the BITMAP_INFO_HEADER_SIZE_V_3 header

try (Image image = Image.load("Sign.bmp"))
{
   image.save("Sign.png");
