Add error handling for failed voice parsing (#59)

The updates in this pull request include:

- Updating the launch.json file to correct the debugging configuration.

- Updating the import statements in __main__.py to use the correct module names.

- Adding error handling for failed voice parsing in download.py. This ensures that any errors encountered during voice parsing are logged and the program continues running.

These changes improve the overall functionality and robustness of the voice downloading utility.
