Provide proper typings for cli.progress()

[divideby0]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

At the moment, cli.progress() takes an option argument of any and returns any. This makes it difficult to validate which options are valid and which operations are available on the result of the function.

There may be a reason that any is specified here. But if it was an oversight, this PR should resolve the issue.
