Subject: [PATCH] cli: Indicate source of a layout when listing

Closes #15

```
$ d2 layout
Available layout engines found:

dagre (bundled) - The directed graph layout library Dagre
tala (~/.local/share/gopath/bin/d2plugin-tala) - Terrastruct's AutoLayout Approach
```

Not as clean but having the source clearly visible is good for
debugging.
