The main goal of this PR is to add a testing workflow to the project’s GitHub Actions to run a set of smoke tests during PRs targeted to main and release branches. Changes include:

• Adding a pytest smoke marker to a variety of tests to be included
  • Base: all
  • CLI: All commands with a --help flag, one or more of each command for a reasonable breadth of coverage
  • Examples: All instances tests where batch size was 1 or 8
• Updating the Makefile to add a target which excludes base tests to better parallelize test runs without overlap
• Create a new GitHub Action workflow to run the base, CLI, and example smoke tests in parallel
