Problems with Parler-TTS Mini Multilingual v1.1

Hi, i love the library and the work your doing!

Recently tried the parler-tts example, works fine for the large-v1 model.

I wanted to try the mini multilingual one but get the following error:

```bash
avx: false, neon: true, simd128: false, f16c: false
temp: 0.00 repeat-penalty: 1.00 repeat-last-n: 64
retrieved the files in 54.020418s
Error: data did not match any variant of untagged enum ModelWrapper at line 699311 column 1
```

Added this modifications to the example:

```rust
let model_id = match args.model_id {
Some(model_id) => model_id.to_string(),
None => match args.which {
Which::LargeV1 => "parler-tts/parler-tts-large-v1".to_string(),
Which::MiniV1 => "parler-tts/parler-tts-mini-v1".to_string(),
Which::Multi => "parler-tts/parler-tts-mini-multilingual-v1.1".to_string(), // added this line
},
};
```

```rust
let model_files = match args.model_file {
Some(m) => vec![m.into()],
None => match args.which {
Which::MiniV1 => vec![repo.get("model.safetensors")?],
Which::Multi => vec![repo.get("model.safetensors")?],
Which::LargeV1 => {
candle_examples::hub_load_safetensors(&repo, "model.safetensors.index.json")?
}
},
};
```

```rust
#[derive(Clone, Debug, Copy, PartialEq, Eq, clap::ValueEnum)]
enum Which {
#[value(name = "large-v1")]
LargeV1,
#[value(name = "mini-v1")]
MiniV1,
#[value(name = "mini-multi")]
Multi,
}
```

And called the tool with
`--which mini-multi`

The download of the `model.safetensors` has worked but then i get an error.

I'am running on an mac with the `--features metal` parameter

Do i have missed something?

Start with the parler-tts example and its model-loading path, using the reported model ID and model.safetensors file as the reproduction. Compare how the multilingual model is loaded with the working large-v1 model and run the example with --which mini-multi and --features metal. Done means the multilingual model loads without the ModelWrapper error or the incompatibility is clearly documented.
