Refactor of _utils.py and associated test cases

[jknndy]

_utils.py

• Expanded on FRACTIONS coverage and TIME_REGEX readability
• Expanded _extract_fractional coverage capabilities. Now handling a wider range of fractional representations specifically unicode fraction characters.
  • Now handles mixed numbers that include unicode fraction characters formatted like 1⅔ by iterating through the FRACTIONS dictionary to find matches & processing separately as needed.
  • Now iterates through FRACTIONS for a match to replace unicode characters
  • Conversion logic located within a try-except block to return a ValueError with a descriptive error message for unrecognized fraction inputs.
  • Improved handling of fractions with and without whole numbers present by checking for existence and processing separately (mixed numbers ('1 1/2') and simple fractions ('1/2')
  • Adjusted some general formatting for consistency throughout code base
• Updated get_minutes for readability and adjusted for new functionality from _extract_fractional
• Updated url_path_to_dict
  • Updated host re.pattern to exclude port / path delimiters.
• Updated get_host_name to use .get
• Updated change_keys
  • Updated to use dictionary comprehension to recursively apply convert to keys.
  • Removed checks for types str, int, float, set, and tuple

library/test_utils.py

• Refactored get_minutes tests into consolidated test cases within TestUtilsRefactored
  • Combined all minute conversion tests into a single method test_minutes_fixtures
  • Isolated ISO 8601 duration format tests into test_iso8601_fixtures
• Implemented setUpClass method in TestUtilsRefactored to allow for further testing expansion.
• Updated test_list_public_methods to dynamically list and compare public methods of AbstractScraper

Updated get_host_name to use .get

This change I'm a little skeptical of - it's an unusual case where I think we'd want the code to break and let us know about it if the host info isn't available. What do you reckon?

Generally looks great, thanks again!

Maybe add 'closes #1004' or 'resolves #1004' to the pull request description to auto-close that bug on merge?

This actually isn't resolved in this update. The FRACTIONS adjustments are only represented in the get_minutes function where the issue in #1004 is related to the ingredients and instructions print outs. Still worth including but I will remove mention of the issue from the PR outline.
