Adding pydantic argparse cli and Refactor Looper Tests

[donaldcampbelljr]

This PR accomplishes these major tasks:

CLI

• Addresses #438 , where we migrate the argument parser to a pydantic-argparse

  TESTS

• major refactoring of the tests to use newest looper config via pulling in PEPs from hello_looper repostory
  • https://github.com/pepkit/hello_looper/pull/15
• Adding the skeleton of new comprehensive smoketests, related to https://github.com/pepkit/looper/issues/464

TODO:

• [x] - adding the remaining arguments
• [x] - ensure they work
• [x] - remove old cli
• [x] - fix tests

Some misc notes on usage by example: looper.cli_pydantic init --force-yes looper.cli_pydantic --looper-config .looper_project.yaml runp looper.cli_pydantic --looper-config .looper.yaml rerun

I had to add init-piface as init_piface. Will revisit.

[donaldcampbelljr]

Commands are added.

These have been refactored and now work with manual testing and some of the original pytest suite.

[donaldcampbelljr]

The original CLI is now removed as well.

I think you're collecting other changes on this PR -- I think you may need to rebase the dev branch into feature-pydantic-argparse-cli, because the incoming branch here is carrying with it a bunch of unrelated updates, making it hard to review the PR

[donaldcampbelljr]

I merged the downstream changes into target branch to make it a bit more legible.

Partially addresses https://github.com/pepkit/looper/issues/464, though there still is work to be done with writing more comprehensive smoketests
