Thanks for the contribution! Made some comments throughout, some of these changes will require test updates. Also once you're done with these be sure to run our test suite locally and the formatter as well. Let me know if you have any questions!

black .\recipe_scrapers\irishcentral.py && python -m unittest

The exception FieldNotProvidedByWebsiteException should only be used when the site never provides the field and should only be used for mandatory fields (not an issue here just mentioning). So there should only be one implementation for total_time in this instance.

@jknndy, I ran the formatter on the .py file, revised with your suggestions, and corrected some of the inconsistent test cases. Please let me know your thoughts.

@jknndy, I am having trouble passing the linter (seemingly due to isort inconsistencies within init.py). I have ran isort recipe_scrapers/__init__.py, which appeared to make several corrections within the file, and am wondering if you might be able to help me understand what else I can do to fix this?

For added context, I was also having isort issues within irishcentral.py; however, after I ran isort on that file, it passed the linter checks right away. Thanks!
