Typing helpers

fleks.util.typing collects common imports and annotation-types, i.e. various optional/composite types used in type-hints, underneath one convenient namespace. This includes stuff from:

• stdlib's typing
• stdlib's types
• pydantics BaseModel's and Field's, etc

>>> from fleks import typing
>>> print(sorted([name for name in dir(typing) if name.title()==name]))
['Annotated', 'Any', 'Awaitable', 'Bool', 'Callable', 'Collection', 'Container', 'Coroutine', 'Counter', 'Deque', 'Dict', 'Field', 'Final', 'Generator', 'Generic', 'Hashable', 'Iterable', 'Iterator', 'List', 'Literal', 'Mapping', 'Match', 'Namespace', 'Optional', 'Pattern', 'Protocol', 'Reversible', 'Sequence', 'Set', 'Sized', 'Text', 'Tuple', 'Type', 'Union']
