Remove hard-coded Factory method calls and (most) direct class instiations

[nosas]

• Partial removal includes:
  • Decouple factory calls and hard-coded object instantiations for: Cog, BattleCogs, BattleEntity, Entity, Gag, ToonAttack
    • See src/factories/utils.py for all decoupled factory calls
  • TODO: Toon, BattleToon, Gags
• Remove hard-coded instantiations in tests
  • Not sure how to proceed in the source code itself just yet without creating an import loop.
  • Perhaps create a factory object in the src?
• Remove redundant factory tests in test_X_creation.py
• Create utils for battle fixtures and factories
• Format changed files with 'black' formatter
• Change factory method prefix from get_ to create_

Future changes may include:

• Develop factory methods for creating Track-specific gags (e.g. create_throw_gag()

All tests passing, let's merge!
