Would you consider adding a Machine-readable progress bar option?

Right now, rich disables progress reporting when something that uses rich is run under a subprocess. This is really inconvenient if you want to have the parent program know how far along the subprocess is.

I implemented a machine-readable progress feature for pip (pypa/pip#12084) and they suggested I ask if this is instead something rich should handle.

Is this something you'd be willing to support?

I'd certainly consider it. If feels like there should be hooks for this, and it should be left up to the developer to decide on the format.
