Single venv creation is not exposed in the CLI
The venvctl's single virtual environment creation is not implemented in the CLI:
The current implementation:
Since the venvctl has a mandatory `config_path` argument in the constructor, `create_venv` is exposed as `classmethod` that returns the class itself and calls its `run` method.
```python
@classmethod
def create_venv(cls, name: str,
packages: List[str],
output_dir: Optional[Path] = None,) -> None:
"""Create a virtual environment."""
config_file = configutils.generate_config(name, packages)
cls(config_file=config_file, output_dir=output_dir).run()
```
The logic behind generates a [config file](https://gitlab.com/hyperd/venvctl/-/blob/development/module/utils/configutils.py#L32) by deserializing a (Venv type)[https://gitlab.com/hyperd/venvctl/-/blob/development/module/main/venv.py], instanciated with a package list and a name. This way the creation process doesn't need to be modified, and even a single venv can benefit of all the reporting and checks.
The method can be called as follows:
`VenvCtl.create_venv(name=name, packages=packages)` where name is a string and packages is a list of strings.
