[RESOLVED] Wayland Issue

I'm using Wayland and Sway, and I had to add this to the root Cargo.toml and update Cargo.lock to get any of the chapters to run:

```toml
[dependencies]
...
x11-dl = "2.21.0"
```

```bash
cargo update -p x11-dl
```

I didn't test every chapter, but chapters 1, 2, and 75 run without problems so far.

Just documenting it in-case anyone else has this issue.
