feat: Add support for as_constraint, remove deprecated methods, move types to subpackages

[Christopher-Chianelli]

• Removed old penalize(constraint_name, ...) overloads
• Removed camelCase names for Joiners and ConstraintCollectors
• Made valuerange and score lazily load types that require the JVM to be started
• Import all subpackages inside the main package so users do not need to import a specific subpackage to use its contents
• Move all classes to specific tempoarily packages. The packages of the classes may change at a later date, but doing this make it easier to do the refactor
• Split up large code files into multiple smaller files
• Deleted the no longer applicable cloning test
• Use star import in tests
