feat: @std/cli should have a progress bar function

[BlackAsLight]

The @std/cli has a spinner function to display the fact that something is loading, likewise we should also have a progress bar function that enables us to show the progress of something happening.

I am in favour of adding this to std.
What should it look like by default and what should be customizable?
There are many different cli progress bar styles in cli land, some with, some without percentage and/or n/m displays, prefixes, suffixes etc.
