CrossInk extras v1.3.0

Shows as 1.6.1-extras 1.3.0 on the reader (CrossInk 1.6.1 with CrossInk extras 1.3.0).

Chapter marks

• Smarter automatic marks: the progress bars now mark the table-of-contents level with a sensible number of entries, so books divided into a few parts mark their chapters instead of just the parts.
• Choose your own: the EPUB Optimizer has a chapter-mark editor. The marks you pick are saved inside the book, and this firmware uses them on the Reading Heatmap and Minimal Carousel progress bars.

Organize your books over USB

• Renaming or moving a book over USB now keeps its reading stats, position and settings. Use it from the new File Manager, or the optimizer's "Replace on reader".

Clearer version name

• The reader now shows "1.6.1-extras 1.3.0" instead of a development build name.
