Recommended flow for refreshing token?

[jghiloni]

Hi! I'd like to be able to log in with the device flow and store the token in a file, along with the refresh token. If the access token is expired, I'd like to refresh. Is there a way to do that with this library? I'm trying to avoid the oauth2 module, as it's more than I need, as I will be doing pure git operations with the go-git module.

If that's what I gotta do, so be it, but if there's something I'm missing that sure would be neat 😃
