    feat: Move 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.
