feat(cli): Adding models subcommand with list and install subcommands (#1165)

Adding subcommands to do certain actions directly from the command line.
I'm starting with the models subcommand allowing you to list models from
your galleries and install them.

This PR partially fixes #816

My intention is to keep adding other subcommands, but I think this is a
good start, and I think this already provides value.

Also, I added a new dependency to generate the progress bar in the
command line, it is not "needed" but I think is a nice to have to have a
cooler interface.

Here is a screenshot:
