This script is somewhat ridiculous. It takes a video and .vtt
subtitles file and converts it to an .epub file with images for each
subtitle. This makes it possible to "read" a TV episode on an E-Ink
tablet, for example.

I made this because I'm not good enough at listening to Japanese at
full speed. Now, I can "read the episode" first, then watch it later.

It will store a file in your user directory to know when the last time
you ran the script was. It then only downloads articles saved after
that day.

* I was encountering an issue where some Wallabag articles didn't have
  all of their content. I overrode the fetch_embedded_article() code,
  but I didn't really change anything and it worked. I commented the
  "isinstance" line, and Wallabag articles do start with text with no
  HTML tags ("Reading time: N minutes"), so maybe that was the fix?
* Added command-line tools to create an epub from the articles. See
  https://github.com/makuto/typhon for a good app for reading these articles
* I included a secret key in the last commit, which is now revoked (so
  don't get any ideas :D )

* The dictionary doesn't really work very well. I abandoned this once
I found Rikai-kun had deconjugators (etc.) that I'm not going to want
to re-implement, so I've moved to relying on their software instead
* I have been adding articles in Japanese to Wallabag for reading
practice. The Calibre rule filters out English articles so I can just
upload Japanese articles to my e-Reader (Onyx Boox Nova 2 running my
modified version of Typhon for dictionary)

* Only libnotify (Linux) notifications are supported so far
* A notification will be triggered every N minutes to study a block

If I only have to study one card every minute, that's very manageable,
even if some build up over busy time.

It runs many times faster, though admittedly was more painful to
write.
I made a C++ version because I might want to have a full SFML
graphical frontend.

I copied my script from https://github.com/makuto/Anki-Romaji-Remover
as a starting point for communicating with Anki.
