SSP server

This crate contains a reference server implementing the SSP protocol for ITL devices.

Running tests

The end-to-end tests require a connected device that supports the SSP/eSSP protocol.

The device should be available over a serial port, e.g. /dev/ttyUSB0.

Once the device is connected:

```

Run the end-to-end tests

cargo test --features test-e2e

Run an example test that cycles all the RGB bezel settings

cargo test --features test-rainbow ```
