-------------------
* josepy is now compliant with PEP-561: type checkers will fetch types from the inline
types annotations when josepy is installed as a dependency in a Python project.
* Added a `field` function to assist in adding type annotations for Fields in classes.
If the field function is used to define a `Field` in a `JSONObjectWithFields` based
class without a type annotation, an error will be raised.
* josepy's tests can no longer be imported under the name josepy, however, they are still
included in the package and you can run them by installing josepy with "tests" extras and
running `python -m pytest`.
