v2.0.0

• Added SortedDictPydanticAnnotation, SortedListPydanticAnnotation, and SortedSetPydanticAnnotation special annotation objects. These can be attached to sortedcontainers' original classes using typing.Annotated to enable Pydantic validation and serialization. See approach 2 in the README for further details.
• Added AnnotatedSortedDict, AnnotatedSortedList, and AnnotatedSortedSet type aliases that can also be used to enable Pydantic validation and serialization. See approach 3 in the README for further details.
• Added support for setting a key function for custom sorting using the Key special annotation object with typing.Annotated. See the relevant section in the README for futher details.
• Added new class SortedKeyList. This is a subclass of both sortedcontainers.SortedKeyList and sortedcontainers_pydantic.SortedList. When using Key with sortedcontainers_pydantic.SortedList, this class will be returned, which is analogous to the behavior with sortedcontainers.SortedList and sortedcontainers.SortedKeyList.
• Removed support for Python 3.8.
