Accretive v2.0 (2024-11-10)

Bugfixes

Add missing alias for reclassify_modules to the qualified aliases module
(qaliases) as reclassify_modules_as_accretive. (#12)

Add ValidatorDictionary and ProducerValidatorDictionary classes.
Validator dictionaries allow a validation function to be supplied, which can
inspect the key and value of a proposed dictionary entry to determine if it
should be accepted or not. Producer dictionaries are like defaultdict from
the standard Python collections module. (#10)
Add py.typed file to package to let typecheckers know that it has a full
set of type annotations. (#11)
Dictionary classes now accept type annonations for key and value. (#14)
Accept a decorators argument with all of the metaclasses to produce classes
which have a sequence of class decorators applied before class attribute
accretion is enforced. Some class decorators are compatible with accretion but
some are not; this gives a way to ensure that they are applied without
attribute enforcement. Advanced cases, such as dataclasses.dataclass( slots = True ), which produces a replacement class, are correctly supported by this
machinery on CPython.
Add ProtocolClass metaclass to produce accretive protocol classes.

Add support for CPython 3.13.
Drop support for CPython 3.8 (past end-of-life).
Drop support for CPython 3.9 (skipping to 3.10, which is the next baseline LTS
version for major OS distributions).
Drop support for PyPy 3.9, which is no longer maintained upstream.

Remove complete, concealment, and protection subpackages to focus
on core value of package: accretive data structures. Users can easily make
their own syntheses as necessary. (#13)
