Git clone a repo with `username` and `password`

Hi, I am trying to use `Repo.clone_from` to git clone a repo. How should I specify `username` and `password` in the code? Thanks a lot!

```python
# example code

from git.repo import Repo

url = "some_url"
path = "some_local_path"
Repo.clone_from(url, path)
```
