This is a one-key WiFi UDP 'keyboard'.

The hardware is a Raspberry Pi Pico in a 3d-printed shell connected to
a Cherry MX switch.

The client software that runs on the device connects to a WiFi network
and sends UDP packets to an address specified in `client/config.c`.
It transmits each keypress several times for reliability, with relative
timestamps so the server can determine the time of every press without
the device needing to synchronize a clock.

The server software collects and de-duplicates keypress reports.
