Mac Support

Would it be possible to add MacOS support? It seems to not be able to interface with USB devices on MacOS

```
thread 'main' panicked at ggoled_cli/src/main.rs:170:33:
called `Result::unwrap()` on an `Err` value: Failed to connect to USB device
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
