removed sample generation

I noticed that the sample generation forces download the "voice-en-us-danny-low" model regardless of user-selected model, and the print voice list command actually causes it to have the following error:

```
File ".../dimits/main.py", line 90, in <listcomp>
    return [[str(asset['name']).split('.')[0] for asset in release['assets'] if asset['name'].startswith('voice')] for release in data][-1]
                                                           ~~~~~~~^^^^^^^^^^
TypeError: string indices must be integers, not 'str'

```
