Wheel: C package to jump buttons

[jr1221]

We need to get the buttons via the ISR to NERO with as little latency as possible. We also have to send out the can message.

Therefore we need a C app that:

1. Uses a GPIO lib to recieve a button press under an ISR
2. Send the status of the button to the VCU
3. Send the button directly to NERO via possibly zenoh.io
