v1.4.5

This is another minor release:

• Extended type checking to tuple and type annotations.
• Removed weakref'ed spec-class instance state that was slowing down instantiation of simple classes by as much as 400%.
• Fixed _GenericAlias catching all errors during setting of __orig_class in Python 3.11+ (preventing Keyed* classes from raising on type errors).
• Migrated to ruff tooling for linting.
