feat: switch to proportional font

To use the available space on the bade more efficient, I changed the
font to u8g2_font_lucasfont_alternate_tf from
[u8g2-fonts](https://docs.rs/crate/u8g2-fonts/).

Lucasfont Alternate was created by Patrick Lauke and is licensed under
[CC BY 3.0](https://creativecommons.org/licenses/by/3.0/).
No changes to the font were made.
