Add --verbose flag to reduce logging to warning+ level, Add Progress bars (#67)

* Add --verbose flag to reduce logging to warning+ level, Add spinner

* Remove spinner, Introduce tqdm, wrapping important loops in tqdm

* Add tqdm to pyproject.toml

* refactor: Add common.py to hold logger and tqdm wrapper, Disable tqdm progress on verbose mode, Remove Unused imports

* Remove extra return

* Apply suggestions from code review

Co-authored-by: Pete LeVasseur <plevasseur@gmail.com>

* Fix logger indentation

* merge --verbose into --debug, remove time.sleep()
