textshaping 1.0.0

• Added lorem_text() and lorem_bidi() for generating nonsense text in
  various scripts
• Added plot_shape() to plot the result of a shaping along with the metrics
• Rewrite of the shaping engine to honor global direction of text. It introduces
  a direction argument to shape_text() that defaults to auto, meaning that
  it is deduced from the content of the shaped text. align gets two new
  settings that responds to the global direction of the text. "auto" will
  chose between "left" and "right" and "justified" will choose between
  "justified-left" and "justified-right" depending of the global direction
  is ltr or rtl. Lastly the soft break locations are now based on ICU and thus
  better support ideographic scripts such as Han/Kanji/Hangul.
• Textshaping now properly supports soft hyphens in that a hyphen is rendered if
  a soft-wrap happens at a soft hyphen (#52)
