Features
--------

- Add scope support.
- Add annotated type hints support (PEP-593).
- Add async injection support.
- Multiple factories can be defined for the same class.
- Cleaner testing support, by separating explicitly the case where test existing
  dependencies or want to create new ones.
- All methods of `Service`, `Factory` and `Constants`
  are automatically wired to support annotated type hints anywhere.

Breaking changes
----------------

- Remove `public` configuration for `Factory` and `Constants`.
  They didn't really bring any value, you hardly hide anything in Python.
- Removed tags. They didn't bring enough value.
- Reworked `inject`: it will only inject annotated type, nothing else anymore.
  `use_type_hint` has been replaced by `auto_provide` and `use_names`
  has been removed.
- Reworked `Constants` to be more flexible.
- Removed `world.singletons`. There was no way to track back where a singleton
  was defined.
- Reworked `Wiring` to be simpler, not super class wiring
