* 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.
Adds a new crate feature `ble` that allows for transfering badge
configurations over Bluetooth Low Energy instead of USB.
Expands the CLI to allow for specification of the transport protocol,
either USB or BLE.
The BLE library uses async rust requiring to add tokio as a async runtime
to the CLI.
