Addresses #28

Clean up code to address pylint errors, in some cases leading to notable refactors => merge as rebase.

[jatkinson1000]

Refactor of handicap params leads to failure of tests due to type hinting not being fully available in python <3.9
See here.

Since 3.7 has reached end of life, and 3.8 has 1 year left this could perhaps be solved by updating rthe supported versions for this library to 3.9+
