fix: pyproject.toml was not valid for Poetry

[Wolfhound905]

The current toml is not supported by Poetry

The Poetry configuration is invalid:
  - [extras.console.0] 'aioconsole>=0.6.0' does not match '^[a-zA-Z-_.0-9]+$'
  - [extras.voice.0] 'PyNaCl>=1.5.0,<1.6' does not match '^[a-zA-Z-_.0-9]+$'

I have adjusted the toml to support Poetry's group dependencies method.

So you can use voice for example by running
poetry install --with voice
