Make braille glyphs with connecting boxes, not dots.

[clort81]

Noting the fact that blind people do not read braille on computer screens..

We conclude that the braille glyphs with connecting blocks are more suitable for terminal applications.

Dot braille is less useful.

Suggest you revise agave to feature box-braille.

Hey clort, thanks for the issue. Personally, I agree, I do like using glyphs in gaming and graphical contexts, but recently in #45 I decided to abide by "ADA Accessibility Guidelines".

I think the way to go would be to provide these as variants (#72) and maybe default to the variant that would see the most use. I've also seen braille used to show quasi-graphical graphs (pretty tops, audio visualisation, etc.), so I do like the dotted variant as well.
