textproc/bookokrat: Add new port
Bookokrat is a terminal-based EPUB reader with a split-view library and reader,
full MathML and image rendering, automatic bookmarks, inline annotations, and
customizable themes.
What you can do:
- Browse every EPUB in the current directory, drill into the table of contents, and resume exactly where you left off.
- Search inside the current chapter or across the whole book, jump through a per-book history, and inspect reading statistics.
- Highlight text, attach comments, copy snippets or entire chapters, and toggle the raw HTML source for debugging.
- Open images in-place, follow internal anchors, launch external links in your browser, and hand off the book to your system viewer.
- Customize with multiple color themes, adjustable margins, and zen mode; settings persist across sessions.
