Add one font that uses unicode box drawing characters

[poetaman]

Modern terminals with unicode support can use box-drawing characters, and they tend to be much more readable. Example is on this page: https://github.com/octobanana/peaclock

I, too, am growing tired of figlet and its many unattractive font options (see also #66). However I'd really like to not make my own font. https://pypi.org/project/python-cfonts/ might be an option, but seems a bit too playful with all the shade effects and such.
