Stop using console.log directly and have all outputs using a standard interface #2
Description
Currently, the Unstack CLI (packages/unstack) is relying on console.log for outputting text in the terminal. That's not ideal as if we wanted to make global changes to outputs, we would have to modify each usage directly.
Therefore, we should at minimum, wrap each usage of console.log present in the CLI code so that when we add more rules/functionality to printing out text, it will be a simpler process.
