Remove Pylint and BasedPyright Errors

[ddmarshall]

These issues need to be addressed:

• ibl_method and thwaites_method classes need to have their typing/linting errors addressed:
  • ibl and thwaites classes have pylint errors too many branches and too many statements.
    • Add BasedPyright to tox
  • mypy takes too long to type-check classes with ibl as parent class
    • This results in the mypy exclusion from tox
• Need to add examples to directories checked by pylint.
  • Several examples have too many variables, too many statement errors
• Add mypy back into tox once found way of addressing time-sink in ibl_method
