Add audio preview generator.

Thread here: https://2dimensions.slack.com/archives/CLLCU09T6/p1707353939433169

The executable will return a non zero code with an error printed on stderr if there's a problem. If the exit code is 0 (success) the output will be JSON like this:

```
{"channels":2,"duration":192.49632263183594,"format":"mp3","sampleRate":44100,"size":8095932}
```

or:

```
{"channels":2,"duration":3.9996354579925537,"format":"wav","sampleRate":96000,"size":2303834}
```

Sample invocation:

```
rive_audio_preview_generator -s ~/Desktop/games_original.wav -d ~/Desktop/games_preview.mp3
```
