Version 0.3.0

API change

• Printer methods return io::Result<usize>

  // Old version
  pub fn raster(&mut self, image: &Image, mode: Option<&str>) -> &mut Self;
  
  // New version
  pub fn raster(&mut self, image: &Image, mode: Option<&str>) -> io::Result<usize>;

• Add related chain API for printer (see: examples/simple.rs)

  // New API
  pub fn chain_raster(&mut self, image: &Image, mode: Option<&str>) -> io::Result<&mut Self>;
  
  // Example
  printer
      .chain_font("C")?
      .chain_align("lt")?
      .chain_style("bu")?
      .chain_size(0, 0)?
      .chain_text("The quick brown fox jumps over the lazy dog")?
      .chain_text("敏捷的棕色狐狸跳过懒狗")?
      .chain_barcode("12345678", "EAN8", "", "", 0, 0)?
      .chain_feed(1)?
      .chain_cut(false)?
      .flush()
