Hi!

I created a package for tagainijisho and its dependency (kanjivg).

I marked this as WIP because I have a few doubts:
- kanjivg distributes an xml file generated by joining xml files stored
  in the repo.  I'm not sure where this xml should be installed
  (under /share/something?)
- kanjivg: guix lint fails with: updater 'github' failed to find
  upstream releases, but I don't know why
- two other xml required by tagainijisho use non-versioned urls, is
  there something we can do about this?

It's the first time I use this program but it seems to be working ok.

Thanks,
Nicolò
